User-assisted file disclosure via unchecked registry paths
Published Jul 20, 2026 · Updated Jul 20, 2026
Path traversal in BKDDFS shamefile before 0.1.7 allows context-dependent attackers to disclose readable file lines via crafted registry data. The shame next snippet renderer trusts each shamefile.yaml location field, opens the referenced path directly, and prints the selected line instead of using cached content. Exploitation requires a user to run shame next in a repository containing attacker-controlled registry data; disclosure is limited to one requested line from a file readable by that user's account.
