Summary
Teleport allows remote authentication bypass
Impact
A full technical disclosure and open-source patch will be published after the embargo period, ending on June 30th, to allow all users to upgrade.
Teleport security engineers identified a critical security vulnerability that could allow remote authentication bypass of Teleport.
Teleport Cloud Infrastructure and CI/CD build, test, and release infrastructure aren’t affected.
For the full mitigation, upgrade both Proxy and Teleport agents. It is strongly recommend updating clients to the released patch versions as a precaution.

The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions. Typical impact: unauthorized data access or execution of privileged operations.
CVE-2025-49825 has a CVSS score of 9.8 (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 (17.5.2, 16.5.12, 15.5.3, 14.4.1, 13.4.27, 12.4.35); 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
Fixed in versions: 17.5.2, 16.5.12, 15.5.3, 14.4.1, 13.4.27, 12.4.35.
These patches are available only on the official Teleport distribution channels.
These versions are designated as Critical Security Exception Versions.
For these specific patch versions of Teleport Community Edition, the Community Edition restrictions are removed on employee count or revenue thresholds, as long as you apply the patch within thirty (30) days of its official release.

Frequently Asked Questions
- What is CVE-2025-49825? CVE-2025-49825 is a critical-severity incorrect authorization vulnerability in github.com/gravitational/teleport (go), affecting versions >= 17.0.0, < 17.5.2. It is fixed in 17.5.2, 16.5.12, 15.5.3, 14.4.1, 13.4.27, 12.4.35. The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions.
- How severe is CVE-2025-49825? CVE-2025-49825 has a CVSS score of 9.8 (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 github.com/gravitational/teleport are affected by CVE-2025-49825? github.com/gravitational/teleport (go) versions >= 17.0.0, < 17.5.2 is affected.
- Is there a fix for CVE-2025-49825? Yes. CVE-2025-49825 is fixed in 17.5.2, 16.5.12, 15.5.3, 14.4.1, 13.4.27, 12.4.35. Upgrade to this version or later.
- Is CVE-2025-49825 exploitable, and should I be worried? Whether CVE-2025-49825 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-2025-49825 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.
