CVE-2026-120201 dromara CVE debrief
CVE-2026-120201 is an authentication bypass vulnerability in Jpom versions 2.10.0 through 2.11.12. Attackers can inject query conditions into the JPOM-USER-TOKEN header to gain super-administrator access and execute commands through Jpom's script features. This vulnerability allows unauthenticated attackers to gain super-administrator access by injecting query conditions into the JPOM-USER-TOKEN header. The vulnerability affects Jpom versions 2.10.0 through 2.11.12 and can be exploited by sending a value like 'is not null', which Hutool's Condition parser treats as an operator.

Who should care
Defenders responsible for Jpom systems should verify versions and restrict access to the JPOM-USER-TOKEN header to prevent exploitation. They should also monitor Jpom systems for suspicious activity and review compensating controls for exposed systems while remediation is scheduled and verified.
Why it matters
CVE-2026-120201 is an authentication bypass vulnerability in Jpom that allows attackers to gain super-administrator access and execute commands. Defenders should verify Jpom versions, restrict access to the JPOM-USER-TOKEN header, and monitor systems for suspicious activity.
- Potential unauthorized access to Jpom systems
- Possible execution of malicious commands through Jpom's script features
- Need for verification of Jpom versions and remediation steps
Technical summary
The CVE-2026-120201 authentication bypass vulnerability in Jpom allows attackers to inject query conditions into the JPOM-USER-TOKEN header to gain super-administrator access and execute commands through Jpom's script features. The vulnerability is caused by the lack of proper validation of the JPOM-USER-TOKEN header, which allows attackers to inject query conditions and gain super-administrator access. The vulnerability affects Jpom versions 2.10.0 through 2.11.12 and can be exploited by sending a value like 'is not null', which Hutool's Condition parser treats as an operator.
Defensive priority
Defenders should prioritize verifying Jpom versions and restricting access to the JPOM-USER-TOKEN header.
Recommended defensive actions
- Verify Jpom versions and ensure they are up-to-date
- Restrict access to the JPOM-USER-TOKEN header
- Monitor Jpom systems for suspicious activity
- 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 details on the authentication bypass vulnerability in Jpom. However, the exact versions affected and the remediation steps are not explicitly stated. The vulnerability is caused by the lack of proper validation of the JPOM-USER-TOKEN header, which allows attackers to inject query conditions and gain super-administrator access.
