This crossed the model/tool-output boundary into a host file read. Prompt injection or malicious tool output is a delivery mechanism; the security boundary failure is the missing local-root containment check.\n\nThe impact is narrow: the file had to be readable by the gateway process, have an audio-like extension, and fit within the webchat audio size cap. The issue exposed contents into the webchat assistant/media transcript path; it was not a general remote filesystem API.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` on npm\n- Affected versions: `<= 2026.4.14`\n- Patched version: `2026.4.15`\n\nThe latest public release, `2026.4.21`, also contains the fix.\n\n## Patches\n\nThe public fix threads the applicable local me","public_affected_ranges":["<= 2026.4.14"]}],"null_published_at":"2026-11-07T07:07:39.867Z","source_updated_at":"2026-05-29T03:47:43.000Z","source_disclosed_at":"2026-04-29T21:34:39.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-07T00:53:22.747Z"}],"next_cursor":null,"snapshot_revision":"42594"}
