What is CVE-2026-8813?
CVE-2026-8813 is a high-severity denial of service vulnerability in exifreader, published on 19 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
This affects versions of the package exifreader before 4.39.0. A crafted image containing an ICC mluc tag can set an attacker-controlled record count together with a zero record size. During parsing, ExifReader repeatedly processes the same record and appends entries to an array without sufficient bounds validation, causing excessive memory growth. In applications that parse attacker-supplied images, this may lead to denial of service through memory exhaustion.
Weakness: CWE-1284
