CVE-2026-41414
The generate-files job in .github/workflows/pr.yml checks out attacker-controlled fork code and executes it via cargo run, with access to SKIM_RS_BOT_PRIVATE_KEY and GITHUB_TOKEN (contents:write).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Skim is a fuzzy finder designed to through files, lines, and commands. The generate-files job in .github/workflows/pr.yml checks out attacker-controlled fork code and executes it via cargo run, with access to SKIM_RS_BOT_PRIVATE_KEY and GITHUB_TOKEN (contents:write). No gates prevent exploitation - any GitHub user can trigger this by opening a pull request from a fork. This vulnerability is fixed with commit bf63404ad51985b00ed304690ba9d477860a5a75.
