Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, A crafted fits stream containing consecutive 2880-byte header blocks without the mandatory end keyword makes fitsinput::read_fits_header() call itself without a depth bound. repeated recursive parsing exhausts the application stack, resulting in denial of service. The affected implementation is identified by src/fits.imageio/fitsinput.cpp, FitsInput::read_fits_header(), END keyword, and 2880-byte FITS header blocks, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1.","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-674"],"references":["https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/b0de7d40d06eb4abc7ef14c1321a1a2a976d8c1c","https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/5248","https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.0.20.0","https://github.com/AcademySoftwareFoundation/OpenImageIO/releases/tag/v3.1.15.0","https://github.com/AcademySoftwareFoundation/OpenImageIO/security/advisories/GHSA-xvwr-x6ch-v2fq"],"products":["openimageio:openimageio"],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-59156","score":0.00363,"percentile":0.30118,"date":"2026-11-01"},"kev":null,"osv":[],"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).
