Hi,

The following vulnerability was published for jpeg-xl.

CVE-2026-82522[0]:
| libjxl before 0.12 contains an integer underflow vulnerability in
| the container box parser that allows remote attackers to inject
| arbitrary metadata by exploiting 64-bit box size truncation to
| size_t on 32-bit platforms. Attackers can supply a crafted JPEG XL
| file causing the decoder to parse attacker-controlled codestream
| bytes as phantom box headers, enabling injection of arbitrary
| metadata (Exif, XMP, IPTC, JUMBF) and potential out-of-bounds reads.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
