Jul 21, 2026Sparkle is a software update framework for macOS.CVE-2026-47122 · Other software · sparkle-project · reported by GitHubMedium 4.2
Sparkle is a software update framework for macOS. In versions up to and including 2.9.1, `Autoupdate/AppInstaller.m`'s `shouldAcceptNewConnection:` only enforces `SUCodeSigningVerifier validateConnection:` before stage 1 completes. After `_performedStage1Installation = YES`, new connections to the registered Mach service `<bundleId>-spki` are accepted from any local process without team-ID or code-signing checks. As of time of publication, no known patched versions are available.

Jul 21, 2026Sparkle is a software update framework for macOS.CVE-2026-47121 · Other software · sparkle-project · reported by GitHubMedium 6.1
Sparkle is a software update framework for macOS. Prior to version 2.9.2, `Autoupdate/SUBinaryDeltaApply.m` enforces `relativePath.pathComponents containsObject:@".."` and rejects writes whose immediate parent directory IS itself a symbolic link, but does not detect symlinks deeper in the relative path. `Autoupdate/SPUSparkleDeltaArchive.m`'s `extractItem:` will create symlinks in the destination tree from archive content (no `..` check on the symlink target), and a subsequent `Extract` item targeting `<symlink>/foo/bar` then escapes the destination tree via `fopen(path, "wb")` because the kernel resolves the intermediate symlink during the open call. This is a defense-in-depth issue: exploitation requires a maliciously-crafted `.delta` that passes EdDSA signature verification, i.e. EdDSA private-key compromise. With the AppInstaller running as root for system-domain installs, it gives the holder of a stolen signing key arbitrary file write at root level via the delta-apply path, which is a strictly broader primitive than the "drop-in replacement bundle" install they would otherwise have. Version 2.9.2 contains a patch for the issue.

Jul 20, 2026ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies.CVE-2026-47134 · Other software · craigjbass · reported by GitHubMedium 6.9
ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. The ECDSA private key used to sign the on-disk policy database (`/Library/Application Support/clearancekit/store.db`) is stored in the macOS System Keychain. The key was created via the two-step pattern `SecKeyCreateRandomKey` (in-memory) followed by `SecItemAdd(kSecValueRef:, kSecAttrAccess:)` (persist). Prior to version 5.0.10, for `kSecClassKey` items in the legacy System Keychain, `kSecAttrAccess` passed to `SecItemAdd` is silently ignored — the persisted key inherits no ACL restriction. The same access builder applied to `kSecClassGenericPassword` items correctly binds the ACL, making this bug specific to the EC key. The result is that any process running as root can use the key to produce valid signatures over arbitrary policy content. Version 5.0.10 fixes the issue. No known workarounds are available. Disabling the system extension and manually removing the System Keychain item labelled `clearancekit policy signing key` would prevent the forged-signature path but also disables policy enforcement.

Jul 20, 2026ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies.CVE-2026-47133 · Other software · craigjbass · reported by GitHubMedium 6.9
ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. Prior to version 5.0.10, each table in the on-disk SQLite policy store (`/Library/Application Support/clearancekit/store.db`) is verified using an ECDSA signature stored in the `data_signatures` table. The signed payload contains only the canonical row content, with no version counter or freshness binding. An attacker who can write `store.db` and the matching `data_signatures` row — feasible during the opfilter-update window when the Endpoint Security filter is offline, or via offline-boot / decrypted-backup scenarios — can substitute a previously-captured legitimately-signed snapshot. opfilter accepts the older snapshot as fully valid on next boot because the existing signatures still verify. Version 5.0.10 patches the issue.

Kopia is a cross-platform backup tool for Windows, macOS, and Linux with fast incremental backups, client-side end-to-end encryption, compression, and data deduplication. Prior to 0.23.0, Kopia's HTTP server started with --without-password accepts unauthenticated requests to /api/v1/repo/exists and forwards attacker-supplied SFTP storage configuration to blob.NewStorage, where externalSSH: true and sshArguments containing -oProxyCommand=<cmd> can cause exec.CommandContext("ssh") to invoke the command through OpenSSH. This issue is fixed in version 0.23.0.

Jul 10, 2026Lima launches Linux virtual machines, typically on macOS, for running containerd.CVE-2026-53657 · Other software · lima-vm · reported by GitHubHigh 8.2
Lima launches Linux virtual machines, typically on macOS, for running containerd. Prior to 2.1.3, on an instance of Lima running with the qemu driver, an arbitrary user in the VM could access /run/lima-guestagent.sock when the guest agent is enabled, which could result in running arbitrary commands with root privileges in the VM because the guest agent socket provides tunneling for arbitrary addresses, including Unix socket addresses for privileged daemons like D-Bus. This issue is fixed in version 2.1.3.

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.
