CVE-2026-4054 SVG content served through Mattermost image proxy despite Content-Type restrictions causes client-side denial of service

Mattermost versions 11.5.x = 11.5.1, 10.11.x = 10.11.13, 11.4.x = 11.4.3 Fail to validate the response body of proxied images, which allows a remote attacker to enact client-side DoS via an SVG file served from an attacker-controlled origin under a non-SVG Content-Type header e.g. image/png...

rkyv: Panic safety bugs in `InlineVec::clear` and `SerVec::clear` enable arbitrary code execution

InlineVec::clear and SerVec::clear in rkyv were not panic-safe. Both functions iterate over their elements and call dropinplace on each, updating self.len only after the loop. If an element's Drop implementation panics during the loop, self.len is left at its original value. A subsequent invocati...

CVE-2026-6210

A flaw was found in Qt SVG. A remote attacker could exploit a vulnerability by providing a specially crafted SVG image. This issue arises from incorrect handling of SVG marker references, where the software misinterprets data types, leading to memory access errors and an infinite loop. This can...
