CVE-2026-55388

piscina is a node.js worker pool implementation. Prior to 6.0.0-rc.2, 5.2.0, and 4.9.3, piscina's constructor and run paths read the filename option via plain member access. Both reads fall through the prototype chain when the caller's options object doesn't have filename as an own property. When...

CVE-2026-55388

Summary: CVE-2026-55388 affects piscina (node.js worker pool). Before versions 6.0.0-rc.2, 5.2.0, and 4.9.3, piscina reads options.filename by plain member access in both the constructor and run() paths, allowing the read to fall through the prototype chain. If Object.prototype.filename is pollut...
