Saloon has insecure deserialization in AccessTokenAuthenticator (object injection / RCE)
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 exe
Saloon has a Fixture Name Path Traversal Vulnerability
Saloon is a PHP library that gives users tools to build API integrations and SDKs. Prior to version 4.0.0, fixture names were used to build file paths under the configured fixture directory without validation. A name containing path segments (e.g. ../traversal or ../../etc/passwd) resulted in a path outside that directory. When the application read a fixture (e.g. for mocking) or wrote one (e.g. when recording responses), it could read or write files anywhere the process had access. If the fixture name was derived from user or attacker-controlled input (e.g. request parameters or config), this constituted a path traversal vulnerability and co
Saloon is vulnerable to SSRF and credential leakage via absolute URL in endpoint overriding base URL
Saloon is a PHP library that gives users tools to build API integrations and SDKs. Prior to version 4.0.0, when building the request URL, Saloon combined the connector's base URL with the request endpoint. If the endpoint was a valid absolute URL, the code used that URL as-is and ignored the base URL. The request—and any authentication headers, cookies, or tokens attached by the connector—was then sent to the attacker-controlled host. If the endpoint could be influenced by user input or configuration (e.g. redirect_uri, callback URL), this allowed server-side request forgery (SSRF) and/or credential leakage to a third-party host. The fix in v
