CVE-2026-81319 MEDIUM PATCH This Month

Unsafe Erlang term deserialization in ash_cloak 0.1.0-0.3.x allows an attacker who can influence encrypted column bytes to crash the BEAM runtime node via unbounded atom table exhaustion or a decompression bomb. Applications configured with Cloak's unauthenticated AES.CTR cipher are the highest-risk targets: an authenticated application user who knows their own plaintext can XOR-derive the keystream and write a forged ciphertext of equal length without the encryption key, causing the deserialization to fire on any subsequent column read. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, but the patch commit confirms two distinct, low-skill attack primitives against unpatched deployments.

CVE-2026-76547 MEDIUM POC PATCH This Month

PHP Object Injection in User Profile Builder WordPress plugin (versions 3.3.4 through before 4.0.1) allows authenticated administrators to inject arbitrary PHP objects by uploading a malicious configuration file through the plugin's import feature. Exploitation is gated by two non-trivial conditions: the affected free add-on must be explicitly enabled (it is disabled by default), and a suitable POP chain gadget must exist in another installed plugin or theme before code execution is achievable. A public POC exists per WPScan, but no public exploit identified at time of analysis maps to confirmed in-the-wild abuse - EPSS sits at just 0.23% (13th percentile), consistent with the high practical bar imposed by admin-level access and gadget dependencies.

CVE-2026-55220 CRITICAL POC PATCH GHSA Act Now

PHP Object Injection leading to remote code execution affects the Pimcore DXP/CMS (composer pimcore/pimcore) in versions 2026.1.0-2026.1.5 and all 12.3.x through 12.3.9, where the Hotspotimage DataObject field marshaller deserializes the persisted `*__hotspots` object-store column with no class allowlist. Any attacker able to write crafted PHP-serialized bytes into that column gains arbitrary object instantiation on the next object load, chainable to RCE via gadgets in Pimcore's own bundled dependencies (guzzlehttp/guzzle 7.11.0). A working proof-of-concept demonstrating attacker-controlled file write is published in the vendor advisory; publicly available exploit code exists, but there is no CISA KEV listing and no EPSS score was provided.

Remote code execution in the Rank Math SEO WordPress plugin (versions <= 1.0.276) is reachable by any user holding WordPress Author-level privileges, exploiting unsafe PHP deserialization (CWE-502) to execute arbitrary server-side code. The CVSS vector (AV:N/AC:L/PR:H) confirms the attack is network-delivered with low complexity once Author credentials are in hand, yielding full confidentiality, integrity, and availability compromise of the host. No active exploitation confirmed in CISA KEV and no public proof-of-concept has been identified in the available intelligence at time of analysis.

CVE-2026-82259 HIGH PATCH This Week

Denial of service in SvelteKit versions 2.49.0 through 2.53.2 is achievable by unauthenticated remote attackers who submit crafted multipart form requests that exploit a deserialization expansion flaw in the experimental `form` remote function, causing the server to construct disproportionately large `files` arrays and exhaust processing resources. Exploitation is gated behind a non-default opt-in flag (`experimental.remoteFunctions: true`) and requires the application to process the `files` array without length or size validation, substantially narrowing real-world exposure despite the CVSS 4.0 score of 8.7. No public exploit has been identified at time of analysis and the vulnerability does not appear in the CISA KEV catalog.

Unauthenticated PHP object injection in the GiveWP WordPress donation plugin (all versions through 4.16.7.1) lets remote attackers reach a deserialization sink and chain it into remote code execution on the hosting server. The flaw is network-reachable with no authentication or user interaction and carries a maximum CVSS of 10.0; Patchstack's public write-up details the full object-injection-to-RCE chain, though no in-the-wild exploitation has been confirmed. Because GiveWP handles donation and payment workflows, a successful attack fully compromises the site and any donor data it processes.

Unauthenticated remote code execution in SOY CMS arises from unsafe deserialization of attacker-controlled data (CWE-502), letting a remote attacker run arbitrary code with the privileges of the web server process. The flaw was coordinated through JPCERT/CC and JVN (JVN04485476) and carries a CVSS 4.0 base score of 9.3. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the deserialization root cause and network-reachable, no-authentication vector make it high priority.

PHP object injection via unsafe deserialization in the User Frontend WordPress plugin (versions before 4.3.10) grants Editor-level users the ability to execute arbitrary PHP code on the host server. The plugin fails to validate field type definitions and deserializes user-controlled post metadata at render time - a CWE-502 flaw exploitable through any available POP chain present in the WordPress environment. A public proof-of-concept exists per WPScan, though SSVC assessment notes no confirmed active exploitation at time of analysis.

All versions of the product are listed as potentially affected per CPE data, with exploitation requiring a valid session holding report administration permissions. No public exploit code or CISA KEV listing has been identified at time of analysis, though the post-authentication command execution capability represents a critical risk for any deployment where report admin credentials can be obtained.

The vulnerability is exploitable by any user holding report administration permissions, making it a significant lateral-movement and post-compromise pivot risk within WatchGuard-managed network environments. No public exploit code or CISA KEV listing has been identified at time of analysis, though the chained SQL injection-to-command-execution primitive is high impact for attackers who have obtained admin-level credentials.
