Impact
The OAuth2 authentication adapter does not correctly validate app IDs when appidField and appIds are configured. During app ID validation, a malformed value is sent to the token introspection endpoint instead of the user's actual access token. Depending on the introspection endpoint's behavior, this could either cause all OAuth2 logins to fail, or allow authentication from disallowed app contexts if the endpoint returns valid-looking data for the malformed request.
Deployments using the OAuth2 adapter with appidField and appIds configured are affected.
Affected versions
Security releases
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 fix corrects the parameter alignment in the OAuth2 adapter's app ID validation method to match the expected interface, ensuring the correct access token is sent to the introspection endpoint.
Frequently Asked Questions
- What is CVE-2026-32269? CVE-2026-32269 is a medium-severity security vulnerability in parse-server (npm), affecting versions >= 9.0.0, < 9.6.0-alpha.13. It is fixed in 9.6.0-alpha.13, 8.6.39.
- Which versions of parse-server are affected by CVE-2026-32269? parse-server (npm) versions >= 9.0.0, < 9.6.0-alpha.13 is affected.
- Is there a fix for CVE-2026-32269? Yes. CVE-2026-32269 is fixed in 9.6.0-alpha.13, 8.6.39. Upgrade to this version or later.
- Is CVE-2026-32269 exploitable, and should I be worried? Whether CVE-2026-32269 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-2026-32269 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.
