CVE-2026-82467 jeremyevans CVE debrief

Who should care

Defenders responsible for Rodauth installations, particularly those using versions prior to 2.47.0, should assess exposure and prioritize updates. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify Rodauth version and exposure in their systems, and monitor for potential redirects to attacker-controlled sites.

Why it matters

CVE-2026-82467 is a medium-severity vulnerability in Rodauth that allows attackers to craft protocol-relative return-to paths, potentially redirecting authenticated users to attacker-controlled sites. Defenders should prioritize verifying and updating Rodauth, assessing exposure, and monitoring for potential redirects.

• Potential for attackers to redirect authenticated users to malicious sites
• Risk of phishing or further exploitation after successful redirects
• Need for verification of Rodauth version and exposure in systems
• Priority for updating Rodauth to version 2.47.0 or later

Technical summary

Rodauth before 2.47.0 fails to validate protocol-relative return-to paths in confirm_password, login_return_to_requested_location, and two_factor_auth_return_to_requested_location features. Attackers can craft paths with leading double slashes that browsers resolve as protocol-relative URLs, redirecting authenticated users to attacker-controlled sites after login or password confirmation. This vulnerability affects Rodauth installations prior to version 2.47.0, and defenders should assess exposure and prioritize updates.

Defensive priority

Defenders should prioritize verifying and updating Rodauth to version 2.47.0 or later, and assess exposure in their systems.

Recommended defensive actions

• Verify Rodauth version and update to 2.47.0 or later if necessary
• Assess exposure in systems using Rodauth
• Monitor for potential redirects to attacker-controlled sites
• 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 vulnerability, including its description and affected versions. However, additional information on exploitation or impact is limited. Defenders should verify Rodauth version and exposure in their systems, and monitor for potential redirects to attacker-controlled sites. The CVE Program record and NVD detail page offer source-provided CVE metadata and vulnerability assessment. There are no known reports of exploitation, but defenders should remain vigilant.
