CVE-2026-33942
CriticalSummary
Saloon to biblioteka PHP, która umożliwia użytkownikom budowanie integracji API i SDK. W wersjach przed 4.0.0 używano funkcji unserialize() w metodzie AccessTokenAuthenticator::unserialize() do przywracania stanu tokena OAuth z pamięci podręcznej lub magazynu, co stwarza ryzyko wstrzyknięcia obiektów.
Risk Assessment
Atakujący, który ma kontrolę nad ciągiem serializowanym, może dostarczyć złośliwy obiekt, co prowadzi do wstrzyknięcia obiektów i potencjalnie do zdalnego wykonania kodu (RCE) w środowiskach z powszechnymi zależnościami.
Recommendation
Zaleca się aktualizację do wersji 4.0.0 lub nowszej, która eliminuje użycie serializacji PHP w klasie AccessTokenAuthenticator, wymagając od użytkowników ręcznego przechowywania i rozwiązywania autoryzatora.

Hazelcast prior to 5.4.5, 5.5.10, and 5.6.1 contains improper validation of data supplied by a malicious client able to connect to a cluster, allowing arbitrary reads from a cluster member's Java heap, off-heap data, and JVM process address space. The same flaw can crash cluster members and, in some Hazelcast Enterprise Edition configurations, corrupt memory with possible arbitrary code execution. This issue is fixed in versions 5.4.5, 5.5.10, 5.6.1, and 5.7.0.
- CVE-2026-107722Critical
fast-jwt from 6.2.0 until 6.3.0 can misclassify RSA public-key text as an HMAC secret when the key has non-whitespace content before its PEM header. In src/crypto.js, performDetectPublicKeyAlgorithms trims whitespace but publicKeyPemMatcher remains start-anchored, so comments, control characters, zero-width characters, or wrapper text can prevent PEM detection and reach the HMAC fallback. An attacker who knows the public key bytes can sign arbitrary HS256 claims with that public material when HS256 is inferred or allowed, resulting in authentication or authorization bypass. An asymmetric-only algorithm allowlist prevents the attack. This issue is fixed in version 6.3.0.
Original NVD description (English source)
Saloon is a PHP library that gives users tools to build API integrations and SDKs. Versions prior to 4.0.0 used PHP's unserialize() in AccessTokenAuthenticator::unserialize() to restore OAuth token state from cache or storage, with allowed_classes => true. An attacker who can control the serialized string (e.g. by overwriting a cached token file or via another injection) can supply a serialized "gadget" object. When unserialize() runs, PHP instantiates that object and runs its magic methods (__wakeup, __destruct, etc.), leading to object injection. In environments with common dependencies (e.g. Monolog), this can be chained to remote code execution (RCE). The fix in version 4.0.0 removes PHP serialization from the AccessTokenAuthenticator class requiring users to store and resolve the authenticator manually.
