ImageMagick: Out-of-bounds Read
CVE-2025-53014 is a critical-severity out-of-bounds read vulnerability in ImageMagick, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected ImageMagick versions: < 7.1.2-0; < 6.9.13-26. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.73% chance of exploitation within 30 days, higher than 55% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of ImageMagick you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
ImageMagick is free and open-source software used for editing and manipulating digital images. Versions prior to 7.1.2-0 and 6.9.13-26 have a heap buffer overflow in the `InterpretImageFilename` function. The issue stems from an off-by-one error that causes out-of-bounds memory access when processing format strings containing consecutive percent signs (`%%`). Versions 7.1.2-0 and 6.9.13-26 fix the issue.

The underlying weakness: Out-of-bounds Read
The product reads data past the end, or before the beginning, of the intended buffer.
How developers prevent this class of flaw
- Use a language that provides appropriate memory abstractions.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
