{"cve":"CVE-2026-112390","nvd":{"published":"2026-10-19T21:17:07.340","modified":"2026-10-23T17:01:18.697","status":"Analyzed","description":"Pillow is a Python imaging library. From 7.2.0 until 13.0.0, Pillow can enter an infinite loop while determining the frame count of a MIC image. MicImageFile inherits TIFF frame traversal, but MicImageFile.tell reports the OLE stream index and its seek() resets TIFF frame state, so an embedded TIFF with at least three IFDs never advances. When an application with olefile installed reads n_frames or saves all frames from a crafted MIC file, the non-advancing traversal can hold a worker at full CPU indefinitely. This issue is fixed in version 13.0.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-835"],"references":["https://github.com/python-pillow/Pillow/commit/26cb3ed061173b817b9ee4b6f507cb0e1e293218","https://github.com/python-pillow/Pillow/releases/tag/13.0.0","https://github.com/python-pillow/Pillow/security/advisories/GHSA-22hg-r758-rrw9","https://github.com/python-pillow/Pillow/security/advisories/GHSA-22hg-r758-rrw9"],"products":["python:pillow"],"source":"nvd","synced_at":"2026-10-24T16:53:35.584907681+00:00"},"epss":{"cve":"CVE-2026-112390","score":0.00593,"percentile":0.48041,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-22hg-r758-rrw9","url":"https://osv.dev/vulnerability/GHSA-22hg-r758-rrw9","summary":"Pillow: Infinite loop in MIC n_frames when the embedded TIFF","modified":"2026-10-26T08:56:03.565713059Z","packages":[{"ecosystem":"PyPI","name":"pillow","purl":"pkg:pypi/pillow","ranges":[">=7.2.0 <13.0.0"],"fixed":["13.0.0"]}]}],"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).
