A malformed input\ncaused the parser to dereference a NULL pointer while applying the\nHilderbrandt transformation.\n\n### Impact\n\nOpen Babel is a C++ library and CLI used to read and write chemistry\nfile formats; it is shipped by Linux distributions and embedded in\nservices that may parse untrusted input. Triggering this vulnerability\nrequires the victim to open a malicious CACAO file with the `obabel`\ntool, the `OBConversion` API, or any of the language bindings (Python,\nRuby, Java, R, Perl, C#, PHP).\n\n### Affected versions\n\nAll releases up to and including 3.1.1.\n\n### Patched version\n\n3.2.0 (released 2026-05-26).\n\n### Patch\n\nFix commit: https://github.com/openbabel/openbabel/commit/ecaed96f\nOriginally reported as #2827; fixes consolidated in #2913.\n\nA minimized reproducer for this CVE is checked in under\n`test/files/fuzz_regress/` and is exercised on every CI build under\nASAN+UBSAN by the `fuzzregresstest` harness.\n\n### Credit\n\nReported via OSS-Fuzz.","public_affected_ranges":["< 3.2.0"]}],"null_published_at":"2026-11-05T19:10:21.450Z","source_updated_at":"2026-07-01T17:41:38.000Z","source_disclosed_at":"2026-07-01T17:41:33.000Z","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":"2026-11-05T03:49:14.191Z"}],"next_cursor":null,"snapshot_revision":"42594"}
