Threat Brief: Critical Vulnerabilities in PHP: CVE-2026-109618, CVE-2026-109619 (Updated October 29)

Unit 42 threat brief on PHP2Shell, two PHP remote code execution flaws, CVE-2026-109618 and CVE-2026-109619 (CVSS 4.0 9.2), both caused by longjmp() error handling that leaves memory uninitialized or freed. Cortex Xpanse counted over 22.6 million exposed instances. The 29 October 2026 update says attackers chained PHP2Shell with a Linux kernel privilege escalation against internet-exposed PAN-OS management interfaces. An earlier 23 October claim of post-compromise activity was retracted on 25 October.

CVE-2026-92885 is a critical (CVSS 3.1 9.8, CWE-287) authentication bypass in the Qode Membership WordPress plugin, versions through 2.0.6.2. A misspelled variable in the Facebook token-verification guard skips provider checks, so an unauthenticated attacker with a public nonce can get a session cookie for an existing account, including an administrator. The post gives the fix (2.0.6.3, bundled in Bridge 30.9), KEV/EPSS/SSVC status, and a SOC log-correlation and remediation plan.

CVE-2026-115905 is a ZIP cloaking flaw in the Rust zip crate (zip-rs/zip2), rated CVSS v4.0 10.0 and affecting versions below 9.0.5. ZipArchive reads central-directory metadata while ZipStreamReader reads local headers, so a crafted archive can pass filename inspection and then overwrite a different file during streaming extraction. Version 9.0.5 adds consistency checks, but ZipStreamReader::new leaves them off by default, and extraction is not atomic, so files can be written before an error is raised. The post covers CWE-20 and CWE-436, KEV and EPSS status, Debian status and a six-step investigation trail.

CISA Adds Two Known Exploited Vulnerabilities to Catalog

CISA added two PHP vulnerabilities to its Known Exploited Vulnerabilities Catalog on 26 October 2026: CVE-2026-109618 (memory corruption) and CVE-2026-109619 (stale internal request state). It also updated its PHP alert on critical vulnerabilities requiring immediate patching. The alert restates BOD 26-04, which requires federal civilian agencies to prioritize fast remediation of KEV CVEs on exposed assets and to check for prior compromise.

CVE-2026-115560 is a PHP code execution bug reported two days after the PHP2Shell emergency patches. The post says those releases do not fix it and no emergency fix is planned. Only apps that switch session.serialize_handler to php via ini_set() before session_start() are exposed.

Official changelog for the Model Context Protocol 2026-07-28 specification. Major changes: protocol-level sessions and the initialize handshake are removed to make MCP stateless, with version and capabilities carried in _meta on every request, plus a new server/discover RPC and subscriptions/listen replacing the GET stream and resource subscribe calls. It introduces Multi Round-Trip Requests (InputRequiredResult) in place of server-initiated sampling, roots and elicitation requests, moves tasks into an extension, and deprecates Roots, Sampling, Logging, HTTP+SSE and Dynamic Client Registration. Minor changes add cache hints (ttlMs/cacheScope), new Mcp-Method/Mcp-Name headers, OpenTelemetry trace context, RFC 9207 iss validation and an error-code allocation policy.

Solidity 0.8.37 Release Announcement

Official release notes for Solidity v0.8.37 detailing three bug-bounty-reported compiler bugs: memory `delete` on a bytes-array element zeroing a full 32-byte word instead of one byte (corrupting adjacent memory, evmasm pipeline, up to v0.8.36); a stack-to-memory spill-slot collision under mutual recursion in the IR pipeline (`--via-ir`, v0.7.2–v0.8.36) that silently overwrites live variables; and named custom-error arguments in `require(...)` being ABI-encoded in call-site order rather than declaration order, so revert data misrepresents error values (v0.8.36 introduced but only affects revert data). Also covers two non-security miscompilations (uninitialized packed function pointers, checked/unchecked constant reuse), a new SSA-CFG stack shuffler, Amsterdam EVM's SLOTNUM opcode support, and removal/deprecation of LSP mode, Generic Solidity, and several EVM version pragmas.
