Summary

CVE-2026-3283 is a low-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Libvips Libvips. Its CVSS base score is 1.9 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 1.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-2 (Flaw Remediation) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2026-3283 is an out-of-bounds read vulnerability in libvips version 8.19.0, affecting the vips_extract_band_build function within the file libvips/conversion/extract.c. The issue arises from manipulation of the extract_band argument, which can trigger improper memory access beyond allocated bounds. This flaw is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-125 (Out-of-bounds Read), with a CVSS v3.1 base score of 3.3.

Exploitation requires local access (AV:L) with low attack complexity (AC:L) and low privileges (PR:L), needing no user interaction (UI:N) and maintaining unchanged scope (S:U). A local attacker could trigger the vulnerability to achieve low-impact confidentiality loss (C:L), such as reading sensitive data from memory, with no impact on integrity (I:N) or availability (A:N). The exploit has been publicly disclosed and may be usable.

Mitigation is available via a patch identified by commit 24795bb3d19d84f7b6f5ed86451ad556c8f2fe70 in the libvips GitHub repository. Security practitioners should deploy this patch promptly to affected libvips installations. Related discussions and the fix are documented in GitHub issues #4880 and pull request #4887.
