Only applications with IAST enabled are affected. IAST is disabled by default.\n\n### Details\n\nThe affected IAST string-processing instrumentation does not properly handle certain internal errors, allowing an error to terminate the application process. Exploitation requires IAST to be enabled and application code to perform an affected string-processing operation on attacker-controlled input.\n\nIf you are unable to upgrade to a patched version of dd-trace-py, you can mitigate this issue by either disabling IAST (setting DD_IAST_ENABLED=false) or by replacing replace % string interpolations with str.format or f-strings for user inputs in your monitored application.\n\n### Proof of concept\n\nDetailed triggering inputs and reproduction steps are omitted from this advisory. The linked fix (#20786) includes regression coverage for the affected behavior.\n\n### Impact\n\nDenial of service affecting applications that use a vulnerable version of dd-trace-py with IAST enabled and expose the affected operation to attacker-contro","public_affected_ranges":[">= 3.13.0, < 4.15.5"]}],"null_published_at":"2026-10-31T22:13:27.125Z","source_updated_at":"2026-10-27T15:37:26.000Z","source_disclosed_at":"2026-10-27T15:37:24.000Z","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":"2026-10-31T21:56:51.534Z"}],"next_cursor":null,"snapshot_revision":"42594"}
