CVE-2026-102555

A flaw was found in libsoup. The soupuridecodedatauri() function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling gbase64decodeinplace(). If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the size of the returned GBytes. This can lead to an out-of-bounds read or application crash when processing a crafted data URI.
