How severe is CVE-2026-32889?

CVE-2026-32889 has a CVSS score of 6.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2026-32889?

CVE-2026-32889 affects the following packages: tinytag (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2026-32889?

Update tinytag to 2.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-32889 is resolved across your whole dependency graph.

How do I detect CVE-2026-32889 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for tinytag. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2026-32889 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2026-32889?

O3 pinpoints whether CVE-2026-32889 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2026-32889 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-32889 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-32889?

CVE-2026-32889 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 33th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-32889?

CVE-2026-32889 is classified as CWE-835 (CWE-835). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2026-32889 published, and has it been updated?

CVE-2026-32889 was published on March 20, 2026 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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.
