How severe is CVE-2023-49793?

CVE-2023-49793 has a CVSS score of 6.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2023-49793?

CVE-2023-49793 affects the following packages: codechecker (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2023-49793?

Update codechecker to 6.23.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-49793 is resolved across your whole dependency graph.

How do I detect CVE-2023-49793 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for codechecker. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2023-49793 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2023-49793?

O3 pinpoints whether CVE-2023-49793 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2023-49793 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-49793, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2023-49793?

CVE-2023-49793 has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 49th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2023-49793?

CVE-2023-49793 is classified as Path Traversal (CWE-22). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2023-49793 published, and has it been updated?

CVE-2023-49793 was published on June 24, 2024 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

CodeChecker is an analyzer tooling, defect database and viewer extension for the Clang Static Analyzer and Clang Tidy. Zip files uploaded to the server endpoint of CodeChecker store are not properly sanitized. An attacker, using a path traversal attack, can load and display files on the machine of CodeChecker server. The vulnerable endpoint is /Default/v6.53/CodeCheckerService@massStoreRun. The path traversal vulnerability allows reading data on the machine of the CodeChecker server, with the same permission level as the CodeChecker server. The attack requires a user account on the CodeChecker server, with permission to store to a server, and view the stored report. This vulnerability has been patched in version 6.23.
