Who should care

Defenders responsible for Company Research Agent deployments should assess exposure and prioritize verification and remediation efforts to prevent potential security breaches. This includes reviewing system configurations, monitoring for suspicious activity, and applying vendor-supported updates or mitigations as needed. Additionally, security teams should review compensating controls and ensure that proper incident response procedures are in place in case

Why it matters

CVE-2026-108850 is a server-side request forgery vulnerability in Company Research Agent through version 2.2.0, allowing unauthenticated attackers to trigger outbound requests. Defenders should prioritize verifying the vulnerability and assessing exposure.

  • Unauthenticated outbound requests can be triggered
  • Leakage of image responses in returned PDFs
  • Probing of reachability via outbound requests

Technical summary

The vulnerability allows unauthenticated attackers to trigger outbound requests by injecting unescaped ReportLab paragraph markup into the /generate-pdf endpoint. This can be used to leak image responses in returned PDFs and probe reachability. The vulnerability is caused by a lack of proper input validation and sanitization in the /generate-pdf endpoint, allowing attackers to inject malicious markup and trigger outbound requests. Defenders should prioritize verifying the vulnerability and assessing exposure to prevent potential security breaches.

Defensive priority

Defenders should prioritize verifying the vulnerability and assessing exposure, as the vulnerability allows for unauthenticated outbound requests.

Recommended defensive actions

  • Verify the version of Company Research Agent and assess exposure
  • Restrict access to the /generate-pdf endpoint
  • Monitor for suspicious outbound requests
  • 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
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
