CVE-2026-100187
AIL Framework Onion Module: Non-Onion URL Accepted as Crawler Task Due to Bypassed Domain Validation
02 Description
AIL Framework Onion Module: Non-Onion URL Accepted as Crawler Task Due to Bypassed Domain Validation
03 Exploitation and scoring
- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 0.43% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 37.3% of scored records. A rank, not a probability.
- NVD base score
- 6.9 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation
The length-based shortcut that bypassed onion-domain validation is removed. Every extracted URL is now parsed using the standard URL domain extraction function, and the resulting hostname is validated against the existing onion-domain validation routine before the URL is added to the crawler task set. This ensures that only URLs whose hostname is a genuine .onion domain can be queued as crawler tasks.
