Summary
Workarounds
There are no known workarounds.
Impact
An attacker with access to a token with few or no scopes can query /api/0/api-tokens/ for a list of all tokens created by a user, including tokens with greater scopes, and use those tokens in other requests.
There is no evidence that the issue was exploited on https://sentry.io. For self-hosted users, it is advised to rotate user auth tokens via https://your-self-hosted-sentry-installation/settings/account/api/auth-tokens/.
CVE-2023-39349 has a CVSS score of 8.1 (High). The vector is network-reachable, low 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 (23.7.2); 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.
Remediation advice
The issue was fixed in https://github.com/getsentry/sentry/pull/53850 and is available in the release 23.7.2 of sentry and self-hosted.
Frequently Asked Questions
- What is CVE-2023-39349? CVE-2023-39349 is a high-severity security vulnerability in sentry (pip), affecting versions >= 22.1.0, < 23.7.2. It is fixed in 23.7.2.
- How severe is CVE-2023-39349? CVE-2023-39349 has a CVSS score of 8.1 (High). 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-2023-39349? sentry (pip) versions >= 22.1.0, < 23.7.2 is affected.
- Is there a fix for CVE-2023-39349? Yes. CVE-2023-39349 is fixed in 23.7.2. Upgrade to this version or later.
- Is CVE-2023-39349 exploitable, and should I be worried? Whether CVE-2023-39349 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-2023-39349 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.
