CVE-2026-26275
HighSummary
W `httpsig-hyper` przed wersją 0.0.23 wystąpił problem z weryfikacją nagłówka Digest, który mógł niepoprawnie zwracać sukces z powodu niewłaściwego użycia makra `matches!` w Rust. W rezultacie, weryfikacja digestu mogła nie wykrywać modyfikacji treści wiadomości HTTP.
Risk Assessment
Organizacje mogą być narażone na ryzyko, że aplikacje polegające na weryfikacji Digest nie wykryją modyfikacji treści wiadomości, co może prowadzić do nieautoryzowanych zmian w danych.
Recommendation
Zaleca się aktualizację `httpsig-hyper` do wersji 0.0.23, aby naprawić problem z weryfikacją digestu oraz wprowadzić dodatkowe warstwy weryfikacji podpisu, jeśli to możliwe.

A vulnerability in the ash_authentication library (Elixir) allows an attacker who can plant a remember-me cookie in a victim's browser to replace the victim's authenticated session with one for the attacker's own account. The issue stems from a mismatch between the session keys used by the guard and the reader, causing remember-me sign-in to run on every request.
Original NVD description (English source)
httpsig-hyper is a hyper extension for http message signatures. An issue was discovered in `httpsig-hyper` prior to version 0.0.23 where Digest header verification could incorrectly succeed due to misuse of Rust's `matches!` macro. Specifically, the comparison `if matches!(digest, _expected_digest)` treated `_expected_digest` as a pattern binding rather than a value comparison, resulting in unconditional success of the match expression. As a consequence, digest verification could incorrectly return success even when the computed digest did not match the expected value. Applications relying on Digest verification as part of HTTP message signature validation may therefore fail to detect message body modification. The severity depends on how the library is integrated and whether additional signature validation layers are enforced. This issue has been fixed in `httpsig-hyper` 0.0.23. The fix replaces the incorrect `matches!` usage with proper value comparison and additionally introduces co
