CVE-2022-24775 is a medium-severity improper input validation vulnerability in guzzlehttp/psr7 (composer), affecting versions < 1.8.4. It is fixed in 1.8.4, 2.1.1.
Impact Improper header parsing. An attacker could sneak in a carriage return character (\r) and pass untrusted values in both the header names and values. Patches The issue is patched in 1.8.4 and 2.1.1. Workarounds There are no known workarounds. References https://www.rfc-editor.org/rfc/rfc7230#section-3.2.4
The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.
CVE-2022-24775 has a CVSS score of 5.3 (Medium). The vector is network-reachable, no privileges required, and no user interaction. 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 (1.8.4, 2.1.1). Upgrading removes the vulnerable code path.

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 instead of chasing every advisory.
Kodem's runtime-powered SCA identifies whether CVE-2022-24775 is reachable in your applications. Explore open-source security for your team.

Yes. CVE-2022-24775 is fixed in 1.8.4, 2.1.1. Upgrade to this version or later.
Whether CVE-2022-24775 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.

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.
