Summary
Impact
A critical vulnerability was discovered in the SAML SSO implementation of Sentry. It was reported to us via our private bug bounty program.
The vulnerability allows an attacker to take over any user account by using a malicious SAML Identity Provider and another organization on the same Sentry instance. The victim email address must be known in order to exploit this vulnerability.
The application does not adequately verify the identity of a user, device, or process before granting access. Typical impact: unauthorized access to functions or data reserved for authenticated parties.
CVE-2025-22146 has a CVSS score of 9.1 (Critical). 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 (25.1.0); 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.
Remediation advice
- Sentry SaaS: The fix was deployed on Jan 14, 2025.
- Self-Hosted Sentry: If only a single organization is allowed (
SENTRY_SINGLE_ORGANIZATION = True), then no action is needed. Otherwise, users should upgrade to version 25.1.0 or higher.
Frequently Asked Questions
- What is CVE-2025-22146? CVE-2025-22146 is a critical-severity improper authentication vulnerability in sentry (pip), affecting versions >= 21.12.0, < 25.1.0. It is fixed in 25.1.0. The application does not adequately verify the identity of a user, device, or process before granting access.
- How severe is CVE-2025-22146? CVE-2025-22146 has a CVSS score of 9.1 (Critical). 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 sentry are affected by CVE-2025-22146? sentry (pip) versions >= 21.12.0, < 25.1.0 is affected.
- Is there a fix for CVE-2025-22146? Yes. CVE-2025-22146 is fixed in 25.1.0. Upgrade to this version or later.
- Is CVE-2025-22146 exploitable, and should I be worried? Whether CVE-2025-22146 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 CVE-2025-22146 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.
