cpython: email header injection due to unquoted newlines

A flaw was found in the email module in the Python standard library. When serializing an email message, the BytesGenerator class fails to properly quote newline characters for email headers. This issue is exploitable when the LiteralHeader class is used as it does not respect email folding rules,...

PT-2026-27227

OpenClaw before 2026.2.22 contains an allowlist bypass vulnerability in system.run that allows attackers to execute non-allowlisted commands by splitting command substitution using shell line-continuation. Attackers can bypass shell-wrapper analysis by injecting $ followed by newline and inside...

GHSA-F8R2-VG7X-GH8M OpenClaw: Exec approval allowlist patterns overmatched on POSIX paths

Summary matchesExecAllowlistPattern normalized patterns and targets with lowercasing and compiled glob matching too broadly on POSIX. In addition, the ? wildcard could match /, which allowed matches to cross path segments. Impact These matching rules could overmatch allowlist entries and permit...

GHSA-5R3V-VC8M-M96G Caddy: Unicode case-folding length expansion causes incorrect split_path index in FastCGI transport

Summary Caddy's FastCGI path splitting logic computes the split index on a lowercased copy of the request path and then uses that byte index to slice the original path. This is unsafe for Unicode because strings.ToLower can change UTF-8 byte length for some characters. As a result, Caddy can deri...

CVE-2026-27590 Caddy: Unicode case-folding length expansion causes incorrect split_path index (SCRIPT_NAME/PATH_INFO confusion) in FastCGI transport

Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, Caddy's FastCGI path splitting logic computes the split index on a lowercased copy of the request path and then uses that byte index to slice the original path. This is unsafe for Unicode because...

Security update for python310

This update for python310 fixes the following issues: CVE-2025-11468: header injection when folding a long comment in an email header containing exclusively unfoldable characters bsc1257029. CVE-2026-0672: HTTP header injection via user-controlled cookie values and parameters when using...

Medium: python3.12

Issue Overview: When folding a long comment in an email header containing exclusively unfoldable characters, the parenthesis would not be preserved. This could be used for injecting headers into email messages where addresses are user-controlled and not sanitized. CVE-2025-11468 User-controlled...

GHSA-G966-83W7-6W38 FrankenPHP's unicode case-folding length expansion causes incorrect split_path index (SCRIPT_NAME/PATH_INFO confusion) in FrankenPHP

Summary FrankenPHP’s CGI path splitting logic improperly handles Unicode characters during case conversion. The logic computes the split index for finding .php on a lowercased copy of the request path but applies that byte index to the original path. Because strings.ToLower in Go can increase the...
