CVE-2025-32781
MEDIUMCVE-2025-32781 is a medium-severity (CVSS 6.5) CWE-639 vulnerability in com.ctrip.framework.apollo:apollo. O3 Security confirms whether CVE-2025-32781 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Apollo: Apollo Portal release endpoint allows cross-application configuration disclosure via releaseId
Blast Radius
com.ctrip.framework.apollo:apolloReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Apollo is a reliable configuration management system suitable for microservice configuration management scenarios. Prior to 2.5.0, Apollo Portal does not verify application and namespace permissions when an authenticated user requests a release by ID through GET /envs/{env}/releases/{releaseId} while configView.memberOnly.envs is enabled, allowing a low-privileged Portal user who obtains or guesses a valid releaseId to read configuration data from other applications and namespaces without calling UserPermissionValidator.shouldHideConfigToCurrentUser(...). This issue is fixed in version 2.5.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.ctrip.framework.apollo:apollo. 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.
Remediation status
No patched version of com.ctrip.framework.apollo:apollo has shipped for CVE-2025-32781 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 O3 protects you
O3 pinpoints whether CVE-2025-32781 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2025-32781. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
