Thumbor is an open-source photo thumbnail service by globo.com. Prior to 7.8.0, the ALLOWEDSOURCES configuration passes plain strings to re.match without escaping dots, so a hostname differing at dot positions can match the allowlist. This issue is fixed in 7.8.0...

CVE-2026-53500

Thumbor (open-source image service by globo.com) is affected prior to version 7.8.0 where ALLOWED_SOURCES is applied by re.match() to unescaped strings, enabling a hostname with dot-position differences to bypass the allowlist. Root cause: unescaped patterns treated as normal strings in a regex m...

re2: Out-of-bounds heap read in `exec`/`test`/`match` via attacker-influenced `lastIndex` on a non-ASCII subject → uncatchable process crash (DoS)

Summary re2 validates the user-settable lastIndex against the subject's UTF-8 byte length but then uses it as a UTF-16 code-unit count to walk the subject buffer, with no bounds check. For any non-ASCII subject, the byte length is larger than the true character count, so a lastIndex between those...

Summary String.prototype.match with a global RE2 collects all matches in a native loop that advances the cursor by the match length. A zero-width empty match has length 0, so the cursor never advances: the same empty match is found forever and appended to an ever-growing native vector. Any patter...
