CVE-2026-33182

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...

CVE-2026-33942

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 allowedclasses = true. An attacker who can control the serialized...

CVE-2026-33183

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 pat...

Server-side Request Forgery (SSRF)

Overview Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the URL construction process. An attacker can cause requests, including authentication headers, cookies, or tokens, to be sent to an attacker-controlled host by supplying a crafted absolute URL as th...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data in the unserialize process of the AccessTokenAuthenticator class when restoring OAuth token state from cache or storage using PHP's unserialize with allowedclasses = true. An attacker can achieve...

CVE-2026-33183

Saloon is a PHP library for API integrations. CVE-2026-33183 (pre‑4.0.0) describes a path-traversal in fixture handling: fixture names could be treated as file paths under the fixture directory, allowing ../ traversal to escape the base directory and read/write arbitrary files if the fixture name...
