CVE-2026-76182 Eclipse Foundation CVE debrief

Who should care

Defenders responsible for Eclipse Jetty deployments, particularly those using TryPathsHandler and TryFilesFilter, should assess exposure and verify affected versions. This includes operators, platform administrators, vulnerability management teams, and security teams who need to ensure that their systems are not vulnerable to this issue and take appropriate measures to mitigate the risk.

Why it matters

CVE-2026-76182 is a vulnerability in Eclipse Jetty that can lead to misinterpretation of URI paths as query parameters. Defenders should prioritize verification of affected versions and configurations, and assess exposure in their systems.

• Potential misinterpretation of URI paths as query parameters
• Verification of affected versions and configurations is necessary
• Assessment of exposure in systems using TryPathsHandler and TryFilesFilter is required

Technical summary

The vulnerability occurs in Eclipse Jetty's `TryPathsHandler` and `TryFilesFilter`, which can be configured to forward requests to template URIs. URI paths may contain characters reserved in URI queries, leading to misinterpretation of paths as query parameters. This can result in unintended query parameter interpretation, potentially affecting the security of systems using these components. Defenders should prioritize verification of affected versions and configurations, and assess exposure in their systems to mitigate potential risks.

Defensive priority

Defenders should prioritize verification of affected versions and configurations, and assess exposure in their systems.

Recommended defensive actions

• Verify affected versions and configurations of Eclipse Jetty
• Assess exposure in systems using TryPathsHandler and TryFilesFilter
• Monitor for potential misinterpretation of URI paths as query parameters
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide limited information about the vulnerability, with no details on exploitation or affected versions. Defenders should verify affected versions and configurations, assess exposure in their systems, and monitor for potential misinterpretation of URI paths as query parameters. The Eclipse Jetty documentation and official advisories should be consulted for detailed information on affected versions and configurations.
