Affected versions
All versions below 1.15.2 are affected. dev-master is fixed starting from https://github.com/SocalNick/ScnSocialAuth/commit/4a00966c41bc37251586d007564c5c891eba3700
Exploits
Because of missing escaping of the URL param redirect a XSS attack is possible.
For example: Setting the redirect param to "><a%20href="http://github.com">GitHub.com</a><inpu%20type="hidden"%20" would result in a link added to the login page.
Resolution
If you are using any version of ScnSocialAuth below 1.15.2 please upgrade immediately by running composer update.
Impact
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.
GHSA-G6F5-4W43-2X63 has a CVSS score of 6.1 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.15.2); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

- How severe is GHSA-G6F5-4W43-2X63? GHSA-G6F5-4W43-2X63 has a CVSS score of 6.1 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of socalnick/scn-social-auth are affected by GHSA-G6F5-4W43-2X63? socalnick/scn-social-auth (composer) versions < 1.15.2 is affected.
- Is there a fix for GHSA-G6F5-4W43-2X63? Yes. GHSA-G6F5-4W43-2X63 is fixed in 1.15.2. Upgrade to this version or later.
- Is GHSA-G6F5-4W43-2X63 exploitable, and should I be worried? Whether GHSA-G6F5-4W43-2X63 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-G6F5-4W43-2X63 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
