{"cve":"CVE-2026-32889","nvd":{"published":"2026-03-20T03:15:59.873","modified":"2026-06-17T10:36:30.997","status":"Analyzed","description":"tinytag is a Python library for reading audio file metadata. Version 2.2.0 allows an attacker who can supply MP3 files for parsing to trigger a non-terminating loop while the library parses an ID3v2 SYLT (synchronized lyrics) frame. In server-side deployments that automatically parse attacker-supplied files, a single 498-byte MP3 can cause the parsing operation to stop making progress and remain busy until the worker or process is terminated. The root cause is that _parse_synced_lyrics assumes _find_string_end_pos always returns a position greater than the current offset. That assumption is false when no string terminator is present in the remaining frame content. This issue has been fixed in version 2.2.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-835"],"references":["https://github.com/tinytag/tinytag/commit/44e496310f7ced8077e9087e3774acbaa324b18a","https://github.com/tinytag/tinytag/commit/4d649b9c314ada8ff8a74e0469e9aadb3acb252a","https://github.com/tinytag/tinytag/commit/5cd321521ff097e41724b601d7e3d7adc7e53402","https://github.com/tinytag/tinytag/security/advisories/GHSA-f4rq-2259-hv29"],"products":["tinytag:tinytag"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-32889","score":0.00426,"percentile":0.36867,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-f4rq-2259-hv29","url":"https://osv.dev/vulnerability/GHSA-f4rq-2259-hv29","summary":"Denial of service via non-terminating SYLT frame parsing loop in tinytag","modified":"2026-07-13T16:43:50.921004109Z","packages":[{"ecosystem":"PyPI","name":"tinytag","purl":"pkg:pypi/tinytag","ranges":["<2.2.1"],"fixed":["2.2.1"]}]},{"id":"PYSEC-2026-3386","url":"https://osv.dev/vulnerability/PYSEC-2026-3386","summary":"Denial of service via non-terminating SYLT frame parsing loop in tinytag","modified":"2026-07-13T16:32:47.106042523Z","packages":[{"ecosystem":"PyPI","name":"tinytag","purl":"pkg:pypi/tinytag","ranges":["<2.2.1"],"fixed":["2.2.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
