{"id":"CVE-2025-26623","aliases":["GHSA-38h4-fx85-qcx7","PYSEC-2026-1353"],"url":"https://o3.security/vulnerability/CVE-2025-26623","summary":"Use After Free in Exiv2","details":"Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. A heap buffer overflow was found in Exiv2 versions v0.28.0 to v0.28.4. Versions prior to v0.28.0, such as v0.27.7, are **not** affected. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The heap overflow is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to gain code execution, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as `fixiso`. The bug is fixed in version v0.28.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.","published":"2025-02-18T19:24:31.701Z","modified":"2026-08-12T03:51:33.535805403Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"exiv2","fixedVersion":"0.28.5"}],"fix":{"url":"https://github.com/Exiv2/exiv2/pull/3174","label":"Exiv2/exiv2#3174"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/26xxx/CVE-2025-26623.json"},{"type":"ADVISORY","url":"https://github.com/Exiv2/exiv2/security/advisories/GHSA-38h4-fx85-qcx7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-26623"},{"type":"REPORT","url":"https://github.com/Exiv2/exiv2/issues/3168"},{"type":"WEB","url":"https://github.com/Exiv2/exiv2/pull/3174"},{"type":"WEB","url":"https://github.com/jim-easterbrook/python-exiv2/commit/4cc875e392f9e0bc705fe03d929b9a382b78dae4"},{"type":"PACKAGE","url":"https://github.com/Exiv2/exiv2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:33.535805403Z"}}
