Sep 14, 2026Description The setuid-root `worker-launcher` binary adjusts ownership and permissions of worker directories by walking the tree with FTS and calling `lchown` CVE-2026-82429 · Websites & servers · Apache Software Foundation · reported by security@apache.orgHigh 7.8
Description The setuid-root `worker-launcher` binary adjusts ownership and permissions of worker directories by walking the tree with FTS and calling `lchown` and `chmod` on each entry's full pathname while running with an effective uid of 0. Both syscalls re-resolve the path at the time of the call, after FTS has classified the entry, and the trees being walked are owned and writable by the untrusted topology user. A tenant running code on a supervisor node could therefore replace an intermediate directory component with a symbolic link between classification and the privileged operation, redirecting the root-owned `lchown` or `chmod` at an arbitrary file on the host. The operation is repeatable at will, since crashing a worker forces a relaunch and blob updates re-run the walk, so a failed attempt costs the attacker nothing. This crosses the boundary that `supervisor.run.worker.as.user` and container isolation are intended to enforce. It is the same defect class as the Hadoop container-executor issues from which this code derives. Mitigation Upgrade to 3.1.0, where the privileged walk operates on file descriptors it has already stat'd rather than on pathnames re-resolved at

Sep 14, 2026Description Dependency artifacts uploaded with `storm jar --artifacts` were stored under a blob key derived only from the Maven coordinate, for example `dep---CVE-2026-82428 · Websites & servers · Apache Software Foundation · reported by security@apache.orgHigh 8.8
Description Dependency artifacts uploaded with `storm jar --artifacts` were stored under a blob key derived only from the Maven coordinate, for example `dep---.jar`. The key was therefore identical for every user of the cluster and predictable in advance. When the blob already existed, the uploader caught `KeyAlreadyExistsException` and silently reused it, with no check that the existing blob's content or owner matched the artifact the submitter had resolved. A user who uploaded a blob under such a key first therefore controlled the bytes that every later submitter of the same coordinate would receive on the worker classpath, resulting in code execution inside another tenant's topology. This affects deployments where more than one principal may create blobs and where the `--artifacts` dependency feature is used. Mitigation Upgrade to 3.1.0, where each uploaded artifact receives a key carrying a freshly generated UUID and a pre-existing blob is no longer silently reused. Note that the corrected key generation is on the SUBMITTING CLIENT, so upgrading the cluster alone does not close this; every client that runs `storm jar --artifacts` must also be upgraded.

Sep 14, 2026Description A topology's `topology.blobstore.map` lets the submitter choose a local name for each blob that the supervisor localises.CVE-2026-82427 · Websites & servers · Apache Software Foundation · reported by security@apache.orgHigh 7.8
Description A topology's `topology.blobstore.map` lets the submitter choose a local name for each blob that the supervisor localises. That name was used to build a path under the topology's working directory without normalisation, in both `AsyncLocalizer` and `Container.createBlobstoreLinks`, and the symlink helper force-deletes whatever already exists at the target before creating the link. A submitter could therefore use `../` segments to direct that delete-and-symlink operation at an arbitrary path, as the supervisor user, on every node the topology is scheduled onto. The consequences include recursive deletion of supervisor-owned content and planting a symlink that causes a subsequent worker launch to execute attacker-chosen code as another tenant's operating-system user, which defeats the isolation that `supervisor.run.worker.as.user` is intended to provide. Mitigation Upgrade to 3.1.0, where the resolved target must lie inside the expected root at both call sites. Users who cannot upgrade immediately should restrict topology submission to trusted principals, and may reject submissions whose `topology.blobstore.map` entries contain path separators or `..` segments before

Description Nimbus accepted the `uploadedJarLocation` argument of `submitTopology` / `submitTopologyWithOpts` as a server-side path and opened it directly, without checking that it referred to a file the caller had actually uploaded. The intended flow is that a client first calls `beginFileUpload`, which returns a path inside the Nimbus inbox, and uploads the jar in chunks to that location; nothing bound submission to that flow, and the `uploaders` map populated by `beginFileUpload` was never consulted at submit time. An authenticated user with topology submission rights could therefore submit any path readable by the Nimbus daemon user as their topology jar. Nimbus copied the file into the topology's jar blob, and the blob ACL grants the submitting subject read access, so the contents could then be retrieved with the ordinary blob download RPCs. Candidate targets include the Nimbus Kerberos keytab, Thrift and UI TLS private keys, and `storm.yaml` with the ZooKeeper authentication payload. Possession of the Nimbus keytab turns an ordinary tenant into a cluster administrator. In a deployment configured as the documentation recommends, submission is available to every authenticate

Sep 14, 2026Description getTopologyPageInfo merged the Nimbus daemon configuration with the topology's own configuration and returned the result without redaction in theCVE-2026-84179 · Websites & servers · Apache Software Foundation · reported by security@apache.orgMedium 6.5
Description getTopologyPageInfo merged the Nimbus daemon configuration with the topology's own configuration and returned the result without redaction in the topology_conf field of TopologyPageInfo. The Storm UI copied that value verbatim into the configuration field of GET /api/v1/topology/{id} and of the corresponding metrics endpoint. Where the cluster is configured with them, the merged map includes storm.zookeeper.auth.payload, which Storm's own documentation directs operators to keep in storm-cluster-auth.yaml under permissions that deny access from workers, together with the keystore and truststore passwords for the Thrift, Netty and ZooKeeper TLS configuration, and any plugin key whose name denotes a secret. getTopologyPageInfo is a topology read-only operation. Under SimpleACLAuthorizer a principal listed in topology.readonly.users or topology.readonly.groups could therefore read daemon credentials that the dedicated cluster configuration API, getNimbusConf, redacts and that is gated on nimbus.users instead. The sibling operations that exist to serve configuration were masked; the topology page, which merges in strictly more daemon state, was not. Mitigation

Description A submitted topology carries two lists of blobstore keys, `dependency_jars` and `dependency_artifacts`, which the client fills in after uploading the corresponding blobs. Nimbus performed no validation of their contents on the submission path, yet acts on them in two places. During cleanup of a finished topology, Nimbus deletes the keys named in those lists, and the deletion is performed as the Nimbus subject, for which the blobstore short-circuits its ACL check. A submitter who listed a key belonging to another topology, such as its `-stormjar.jar`, could therefore cause that blob to be deleted when their own topology was cleaned up. Separately, on acquiring leadership a Nimbus compares the dependency keys of all active topologies against the blobstore contents and surrenders leadership if any is missing. A single key that does not exist, on a single active topology, therefore causes every Nimbus to acquire leadership, surrender it and requeue indefinitely, leaving the cluster without a leader and unable to schedule, clean up or accept submissions. Mitigation Upgrade to 3.1.0, where a submission is refused unless every entry in both lists is a dependency blob key

Sep 14, 2026Description The DRPC server kept a map from function name to request queue and created an entry the first time a function name was seen.CVE-2026-82439 · Websites & servers · Apache Software Foundation · reported by security@apache.orgCritical 9.8
Description The DRPC server kept a map from function name to request queue and created an entry the first time a function name was seen. No code path ever removed an entry: request cleanup removed the request from its queue, and the shutdown path drained queues, but the queue object and its map entry remained for the life of the process. Function names come from the client and are not constrained to functions any topology has registered, so the number of retained entries is bounded only by the number of distinct names an attacker chooses to send, and each retained entry holds the name itself. `drpc.authorizer` is unset by default, so no credentials are required to reach the endpoint. The retained state is permanent rather than a transient load spike, so the effect accumulates until the DRPC server exhausts its heap. Mitigation Upgrade to 3.1.0, where a function's queue is removed once nothing is waiting in it. Users who cannot upgrade immediately should configure `drpc.authorizer` so that only trusted principals can reach the DRPC endpoints, and should ensure the DRPC ports are not reachable from untrusted networks.

Concrete CMS RSS Displayer block below version 9.5.3 rendered remote feed item titles without HTML escaping, resulting in stored cross-site scripting. An attacker able to control a title in a syndicated feed could execute script in the site origin for any visitor to the affected page, including administrators, without holding an account on that site. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 6.0 with vector CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks riodrwn for reporting.

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the user 'donationLink' profile field. User::setDonationLink() (objects/user.php) stores the value and save() validates it only with filter_var(..., FILTER_VALIDATE_URL), which accepts strings such as http://evil.example/"onmouseover=alert(document.domain)//, while getDonationLink() applies only strip_tags() and does not encode double quotes. plugin/CustomizeUser/actionButton.php echoes the value unencoded into an <a href="..."> attribute, and that button is included from view/modeYoutubeBottom.php on the watch page when the CustomizeUser option allowDonationLink is enabled. An authenticated user who updates their own profile via objects/userUpdate.json.php can therefore break out of the href attribute and inject an event handler that executes JavaScript in the browser of any visitor—including an administrator—who views the attacker's videos and interacts with (for example, hovers over) the donation button. The issue was unfixed at the time of reporting.

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a reflected cross-site scripting vulnerability in plugin/Live/confirmLivePassword.php. The script interpolates the unauthenticated GET parameter u (which is not covered by $securityFilter) directly into an <img src="..."> attribute without URL- or HTML-encoding. A remote attacker can craft a link containing a double-quote character in u (with a non-empty key parameter and no valid c parameter) to close the src attribute and inject an additional tag with an onerror handler, executing arbitrary JavaScript in the site's origin in the browser of any user, including an administrator, who opens the link.
