CVE-2026-108605 jeecgboot CVE debrief

Who should care

System administrators, security teams, and developers responsible for JeecgBoot deployments should assess exposure and prioritize remediation to prevent potential corruption of OCR results.

Why it matters

CVE-2026-108605 is a missing authorization vulnerability in JeecgBoot through 3.9.5 that allows authenticated users with low privileges to modify global OCR templates, potentially corrupting OCR results for all users. System administrators and security teams should assess exposure and prioritize remediation.

• Authenticated users with low privileges can modify global OCR templates, potentially corrupting OCR results for all users.
• System administrators and security teams need to assess exposure and prioritize remediation to prevent potential corruption of OCR results.
• Verification of vendor remediation and application of patches or updates is necessary to mitigate the vulnerability.

Technical summary

The AiOcrController updateById handler in JeecgBoot through 3.9.5 does not properly authorize requests, allowing authenticated users with low privileges to modify global OCR templates by sending PUT requests to /airag/ocr/edit. This can corrupt OCR results for all users. The vulnerability has a CVSS score of 5.3 and a severity of MEDIUM. The affected product is JeecgBoot, and the vulnerability is classified as a missing authorization vulnerability. The CVE record and NVD entry provide details on the vulnerability, but the scope of affected versions and remediation steps require verification from official sources.

Defensive priority

Authenticated users with low privileges can exploit this vulnerability, making it essential for system administrators and security teams to assess exposure and prioritize remediation.

Recommended defensive actions

• Assess exposure by verifying if the AiOcrController updateById handler is accessible to authenticated users with low privileges.
• Review and restrict access to the /airag/ocr/edit endpoint to prevent unauthorized modifications.
• Monitor for suspicious PUT requests to /airag/ocr/edit and implement logging and alerting.
• Verify vendor remediation and apply patches or updates as necessary.
• 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.
