CVE-2026-40311: ImageMagick: Heap-use-after-free via XMP profile could result in a crash when printing values

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: imagemagick (Debian:12) 8:6.9.11.60+dfsg-1.6+deb12u9; imagemagick (Debian:13) 8:7.1.1.43+dfsg1-1+deb13u8; imagemagick (Debian:14) 8:7.1.2.19+dfsg1-1.

Low priority for now. Upgrade to imagemagick (Debian:12) 8:6.9.11.60+dfsg-1.6+deb12u9; imagemagick (Debian:13) 8:7.1.1.43+dfsg1-1+deb13u8; imagemagick (Debian:14) 8:7.1.2.19+dfsg1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

ImageMagick is free and open-source software used for editing and manipulating digital images. Versions below 7.1.2-19 and 6.9.13-44 contain a heap use-after-free vulnerability that can cause a crash when reading and printing values from an invalid XMP profile. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19.
