Rapid7 analysis of CVE-2026-97229, a CVSS 10.0 integer overflow (CWE-190) in the Onigmo regex compiler used by GitLab CE/EE's CI/CD regex handling. A crafted regex in a .gitlab-ci.yml passes validation as US-ASCII, then is recompiled for a UTF-8 repository path, producing invalid instructions that give code execution as the git user. Rapid7 reproduced it on GitLab CE 19.4.1 with ASLR (patched in 19.4.2); despite the vendor's "unauthenticated" rating, the attacker needs to commit a malicious config to a public project, which self-registration allows. No in-the-wild exploitation is confirmed, and Rapid7 recommends urgent upgrades.

Rootshell Security Bulletin #22 (Aug 1998) reports an ICQ authentication flaw found by a Linux ICQ clone developer. The Mirabilis server stores 8-character passwords, and sending a password of 9 or more characters (e.g. "123456789") overflows the buffer and logs the client in as any UIN not already online. This gives full account takeover, including receiving offline messages. It is not spoofing, and it works with unofficial clients such as zicq, since the official client enforces the length limit client-side.

Analysis of CVE-2026-88779 (CVSS v4.0 8.7), an unauthenticated memory-overflow flaw in the nsaaad SAML authentication handler on Citrix NetScaler ADC/Gateway that lets attackers crash the SAML service and lock out VPN/SSO access indefinitely through repeated triggering. Affects NetScaler 14.1 before 14.1-73.41 and 13.1 before 13.1-64.28 (plus FIPS/NDcPP builds); watchTowr Labs reproduced it via honeypot activity, Citrix confirmed targeted in-the-wild exploitation from IP 213.209.159.55, and CISA added it to KEV on 2026-10-04 with an Oct 7 federal remediation deadline. Some researchers suspect the overflow could extend to RCE beyond the documented DoS, though Citrix hasn't confirmed this.

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.

GHSA-v234-4jrq-mgg6 discloses that Claude Desktop for macOS (versions >=1.1.3918, less than 1.15962.0) omitted a macOS-executable file type from its Cowork folder block-list, letting a malicious file written into a Cowork sandbox's shared folder by a compromised or prompt-injected agent run commands on the host when opened via Claude Desktop. A separate, compounding issue is also disclosed: Cowork VM images before 1.11847.5 shipped a guest Linux kernel vulnerable to CVE-2026-43284, which combined with the block-list gap could let VM-privileged code trigger the file open without user interaction. Both issues are fixed in Claude Desktop 1.15962.0; reported internally by Anthropic and independently by Vladimir Tokarev of Cyera Research.

CVE-2026-87902 (CVSS 9.2) is an unauthenticated WordPress vulnerability where get_page_template() page-template resolution can be tricked into including an attacker-chosen local .php file outside the active theme directory, leading to RCE when a theme has a page-* top-level directory and a readable local PHP file (e.g. pearcmd.php) exists. Attackers began exploiting it within hours of the September 22, 2026 patch, including pearcmd.php to write PHP web shells to /tmp and /var/tmp and pulling a GitHub-hosted uploader payload, per honeypot telemetry from Previdian and Patchstack with tracked source IPs. CISA added the flaw to its KEV catalog on September 25, 2026, mandating FCEB remediation by September 28; fixed in WordPress 7.1.2, 7.0.6, 6.9.9, and 6.8.10.

GitHub Security Advisory (CVE-2026-13341) for Kong's mcp-konnect MCP server describes a stored prompt injection vulnerability where a remote attacker crafts malicious request metadata (e.g. User-Agent) that gets stored in Konnect analytics and later returned unsanitized to an AI assistant via MCP tools, potentially causing the agent to exfiltrate sensitive data (plugin configs, secrets, internal hostnames) to an attacker-controlled URL if the client can make outbound fetches. A related path manipulation flaw in control plane/group identifiers allowed requesting unintended Konnect API endpoints with the user's token. The v1.0.0 patch neutralizes untrusted analytics fields, validates identifiers as UUIDs, encodes path segments, and disables raw plugin config output by default.

VulDB entry for CVE-2026-90617, a remote OS command injection (CWE-78) in GH05TCREW PentestAgent. The flaw is in run_task in interface/main.py of the MCP HTTP Server, affects everything up to commit cf882dab, and has a public exploit. The product uses rolling releases, so no version ranges exist, and the fix is an unmerged pull request. The analysis suggests compensating controls: restrict network access to the MCP server, run with least privilege, and validate input upstream.
