Astra Linux - уязвимость в python3.11, python3.7

The email module, specifically the “BytesGenerator” class, did not properly quote newlines for email headers when serializing an email message. This issue occurs only when using “LiteralHeader” to write headers that do not follow email folding rules. The new behavior will reject incorrectly folde...

CVE-2026-26962

Rack is a modular Ruby web server interface. From version 3.2.0 to before version 3.2.6, Rack::Multipart::Parser unfolds folded multipart part headers incorrectly. When a multipart header contains an obs-fold sequence, Rack preserves the embedded CRLF in parsed parameter values such as filename o...

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...
