  • Oct 6, 2026Handlebars provides the power necessary to let users build semantic templates.CVE-2026-106444 · Other software · handlebars-lang · reported by GitHubMedium 4.7

    Handlebars provides the power necessary to let users build semantic templates. From 4.0.0 until 4.7.10, Handlebars.precompile() uses quotedString() in lib/handlebars/compiler/code-gen.js to emit static template text into generated JavaScript without escaping sequences that terminate an enclosing HTML script element. When an application precompiles attacker-controlled template text and embeds the generated source directly in an inline script element, a closing script delimiter can end the element and cause following attacker-controlled markup to be parsed and executed. Ordinary server-side rendering and precompiled templates served as external JavaScript files are not affected. This issue is fixed in version 4.7.10.

    A heap-based buffer overflow was found in GIMP’s DICOM export plug-in. When exporting an image with extremely large width and height, the export path allocates a buffer using a 32-bit width * height (and bytes-per-pixel) product that can overflow. GEGL then writes the full uncompressed extent into the undersized buffer, after integer overflow in the allocation size

    Gitea validated the initial remote URL for push mirrors, wiki remote checks, and fetches of migrated pull request heads, but the subsequent raw Git operations followed HTTP redirects without revalidating the destination. A repository administrator using a policy-allowed endpoint that redirects could make Gitea's Git client send requests to an address that the outbound host policy would otherwise block. The impact depends on the configured policy and the internal services reachable from the server.

    Gitea Actions blocks the jobs of workflow runs from first-time fork pull request contributors until a maintainer approves the run. The rerun path only required a run to be finished and built the new attempt's jobs without considering the pending approval, so when a user with Actions write access cancelled a run that was awaiting approval and then re-ran it, the new jobs were created as waiting rather than blocked while the run still recorded that approval was required. Cancelling and re-running stale fork checks is a routine action that does not involve the approval control, so where Actions is enabled and a matching runner is registered, workflow code taken from the fork pull request head could run on the repository's runners without an explicit approval.

    A user who can open a fork pull request can place workflow content with a shared run-level concurrency group into a Gitea Actions run that is awaiting approval. When a later run in that group cancels the blocked job, the run becomes terminal while still marked as needing approval. If a maintainer later approves the run, Gitea passed the already-cancelled job back through concurrency preparation, set it to waiting, and made it claimable by a matching runner, executing fork-controlled workflow code. Exploitation requires the maintainer's later approval action, Actions to be enabled, and a runner that accepts the repository's jobs.

    When a Gitea Actions run was inserted, older runs in the same workflow-level concurrency group were cancelled without checking whether the new run still needed approval. Because fork pull request runs are inserted under the base repository, a user who can open a pull request from a fork could cancel trusted in-progress runs that share a concurrency group with `cancel-in-progress` enabled, without approval and without running any code. On self-hosted runners this can interrupt deployments and leave partial state behind.

    Authorization Bypass Through User-Controlled Key (CWE-639) in Elasticsearch can lead to Information Disclosure via a specially crafted cross-cluster search request that references an unauthorized shard identifier. Elasticsearch contains an authorization bypass weakness in its handling of cross-cluster search requests made through the Remote Cluster Security (RCS) 2.0 model. An authorization check validates a request against one identifying attribute of the target shard, while a separate, independently-supplied identifying attribute in the same request determines which shard is actually accessed. A holder of a cross-cluster API key authorized for one index can craft a request whose two identifying attributes refer to different indices, causing the request to be authorized against an index they can access while actually operating against a different, unauthorized index. This can expose that index's document contents, field mappings, and other metadata, and in limited cases allows modification of retention-lease state on the unauthorized index.

    Uncontrolled Recursion (CWE-674) in Elasticsearch can lead to Denial of Service via a specially crafted request that causes the server to construct and process a deeply nested data structure with no bound on recursion depth. Elasticsearch contains an uncontrolled recursion weakness in how it builds and serializes geometry values produced by scripted runtime fields. Unlike geometry supplied as text, which is subject to a nesting-depth limit, geometry constructed from a script's output is not bounded. An authenticated user with read access to a single index can submit a request defining such a field with a script that produces a deeply nested structure. Processing this request recurses past the available stack space, causing the affected node to terminate. The node does not recover automatically on all deployments and may require manual intervention to restore service.

    Incorrect Authorization (CWE-863) in Elasticsearch can lead to Privilege Escalation via a delegated administrative privilege whose scope is not fully enforced during authorization checks. Elasticsearch contains an incorrect authorization weakness in a configurable, non-default privilege that lets an administrator delegate limited role-management capability to another user, scoped to specific indices. The authorization check that enforces this scoping does not correctly account for a role-definition setting that can expand the matched index set. A user holding this delegated privilege with a broadly-scoped index pattern can exploit this inconsistency by updating their own assigned role to gain access to indices that should remain restricted, including internal security data. This can enable further escalation up to full administrative control of the cluster.

    Allocation of Resources Without Limits or Throttling (CWE-770) in Elasticsearch can lead to Denial of Service via Excessive Allocation (CAPEC-130). Elasticsearch enforces a size limit on the user-supplied metadata field for each individual template resource, but does not limit the total memory used when multiple such resources are retrieved together. A user holding the *manage_index_templates* cluster privilege can register multiple resources each within the individual limit.

    Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana could lead to cross-tenant data interception. In this context, "tenant" refers to a user or team sharing the same Kibana deployment, not a separate Elastic Cloud organization or customer. Kibana's Fleet package installation process allowed a user holding delegated Fleet package-management privileges, without direct Elasticsearch administrative privileges, to claim a data stream identifier already in use by another tenant. Because ownership of that identifier was not verified before Fleet applied the uploaded package's generated index and ingest-pipeline settings to already-existing infrastructure, an attacker could redirect an existing tenant's data stream through infrastructure under their control. This exposed the affected tenant's subsequently ingested data to unauthorized disclosure and modification, and prevented that data from reaching its intended destination. Interception could continue even after the malicious package was removed, requiring separate remediation of the affected infrastructure.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
