CVE-2026-53466: ImageMagick: Heap Buffer Over-Read in XCF decoder due to integer conversion overflow

Noroxi assessment

Priority: Monitor (action score 26/100)

  • 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: 0.22% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: imagemagick (Alpine:v3.23) 7.1.2.27-r0; imagemagick (Debian:12) 8:6.9.11.60+dfsg-1.6+deb12u12; imagemagick (Debian:13) 8:7.1.1.43+dfsg1-1+deb13u11.

Low priority for now. Upgrade to imagemagick (Alpine:v3.23) 7.1.2.27-r0; imagemagick (Debian:12) 8:6.9.11.60+dfsg-1.6+deb12u12; imagemagick (Debian:13) 8:7.1.1.43+dfsg1-1+deb13u11 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. Prior to versions 6.9.13-51 and 7.1.2-26, an integer overflow in the XCF decoder can result in an out of bounds read when a crafted image is read, potentially resulting in a crash. This issue has been fixed in versions 6.9.13-51 and 7.1.2-26.
