CVE-2026-112005 clidey CVE debrief

Who should care

Defenders responsible for systems using WhoDB versions between 0.104.0 and 0.135.0 should assess exposure and potential impact. They should verify if the system uses affected versions, evaluate if attackers could exploit the vulnerability to read and write arbitrary host files, and apply patches or updates to prevent exploitation. Additionally, defenders should monitor for suspicious activity related to DuckDB filesystem functions.

Why it matters

CVE-2026-112005 is a critical vulnerability in WhoDB 0.104.0 before 0.135.0 that allows remote attackers to read and write arbitrary host files through DuckDB filesystem functions in the query editor.

• Verify exposure by checking if the system uses WhoDB versions between 0.104.0 and 0.135.0
• Assess potential impact by evaluating if attackers could exploit the vulnerability to read and write arbitrary host files
• Apply patches or updates to WhoDB to prevent exploitation
• Monitor for suspicious activity related to DuckDB filesystem functions

Technical summary

The WhoDB 0.104.0 before 0.135.0 contains a path traversal vulnerability that allows remote attackers to read and write arbitrary host files by running DuckDB filesystem functions through the query editor. The vulnerability has a critical CVSS score of 9.2 and is considered high severity. Defenders should prioritize verifying exposure and assessing potential impact. Evidence from official sources indicates a path traversal vulnerability in WhoDB 0.104.0 before 0.135.0, allowing remote attackers to read and write arbitrary host files through DuckDB filesystem functions in the query editor.

Defensive priority

Defenders should prioritize verifying exposure and assessing potential impact

Recommended defensive actions

• Verify exposure by checking if the system uses WhoDB versions between 0.104.0 and 0.135.0
• Assess potential impact by evaluating if attackers could exploit the vulnerability to read and write arbitrary host files
• Apply patches or updates to WhoDB to prevent exploitation
• Monitor for suspicious activity related to DuckDB filesystem functions
• 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.

Evidence notes
