CVE-2026-55086

Etherpad (ep_etherpad-lite) versions prior to 3.1.0 are vulnerable to a symlink-based file overwrite via predictable temporary filenames. The ImportHandler.ts and ExportHandler.ts components derive temp-file paths from Math.random() (~32 bits of entropy), which is predictable within the same Node...

GHSA-2JWF-F4XQ-F24H ep_etherpad-lite: Import/export uses Math.random() for temp file paths; predictable paths on shared /tmp enable symlink-based file overwrite

Description src/node/handler/ImportHandler.ts and src/node/handler/ExportHandler.ts both compute their temporary working-file paths as: ts const randNum = Math.floorMath.random 0xFFFFFFFF; const srcFile = $os.tmpdir/etherpadexport$randNum.html; const destFile =...

Name of the Vulnerable Software and Affected Versions Etherpad versions prior to 3.1.0 Description Files src/node/handler/ImportHandler.ts and src/node/handler/ExportHandler.ts generate temporary filenames using Math.random, which is not cryptographically secure and predictable across calls withi...
