# Security digest: October 17, 2025

1 editorial brief and 3 critical advisories.

## Take stock

- Check exposure: GlassWorm . Developers using Cursor, Windsurf, VSCodium, Gitpod/Theia or other Open VSX-backed editors who installed any listed extension, or any lookalike 'AI assistant' extension from an unfamiliar publisher.
- PyPI: 2 critical advisories ( pyquokka , keras ). Check with pip-audit (or: pip show <package>) .
- Maven: 1 critical advisory ( net.mingsoft:ms-mcms ). Check with mvn dependency:tree -Dincludes=<groupId>:<artifactId> .
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

- **Check exposure** [GlassWorm: Invisible-Unicode Malware in Open VSX Extensions](https://erroneo.us/security/briefs/glassworm-open-vsx-extension-malware/index.md): This is a recurring campaign rather than a single event; developers on VS Code forks that pull from Open VSX should audit installed extensions and auto-updates, while most stock VS Code users with mainstream extensions were not affected.

## Known exploited (CISA KEV)

None.

## Critical advisories

- [CVE-2025-62515](https://erroneo.us/security/cve/CVE-2025-62515/index.md) pyquokka is Vulnerable to Remote Code Execution by Pickle Deserialization via FlightServer — PyPI pyquokka <= 0.3.1 → no fix
- [CVE-2025-49655](https://erroneo.us/security/cve/CVE-2025-49655/index.md) Keras framework vulnerable to deserialization of untrusted data — PyPI keras >= 3.11.0, < 3.11.3 → 3.11.3
- [CVE-2025-56316](https://erroneo.us/security/cve/CVE-2025-56316/index.md) MCMS vulnerable SQL injection via the content_title parameter — Maven net.mingsoft:ms-mcms >= 5.5.0, < 6.0.2 → 6.0.2
