CVE-2026-82262 logto-io CVE debrief

Who should care

Tenant administrators and defenders responsible for Logto installations should be aware of this vulnerability and assess their exposure. They should verify the version of Logto in use and consider implementing additional security controls to prevent SSRF attacks.

Why it matters

CVE-2026-82262 is a server-side request forgery vulnerability in Logto through version 1.42.0. Defenders should prioritize verifying exposure, especially in environments where tenant administrators have Management API tokens, and assess the network exposure of Logto and potential impact on internal services.

• Potential unauthorized access to internal services
• Possible data breaches due to SSRF attacks
• Need for verification of Logto version and exposure
• Potential disruption of internal services due to SSRF attacks

Technical summary

The vulnerability exists in the POST /api/hooks/:id/test endpoint of Logto through version 1.42.0. The endpoint accepts arbitrary URLs without host validation, allowing tenant administrators with Management API tokens to make the server issue HTTP POST requests to internal URLs and retrieve response bodies from services on the private network. This could lead to unauthorized access to internal services, potential data breaches, and disruption of internal services due to SSRF attacks. Defenders should prioritize verifying exposure of Logto installations to this vulnerability, especially in environments where tenant administrators have Management API tokens. They should also assess the network exposure of Logto,

Defensive priority

Defenders should prioritize verifying exposure of Logto installations to this vulnerability, especially in environments where tenant administrators have Management API tokens. They should also assess the network exposure of Logto and the potential impact of SSRF attacks on internal services.

Recommended defensive actions

• Verify the version of Logto in use and assess exposure to this vulnerability.
• Restrict Management API tokens to minimize the impact of potential SSRF attacks.
• Monitor network traffic and logs for suspicious activity related to the POST /api/hooks/:id/test endpoint.
• Consider implementing additional security controls, such as IP blocking or traffic filtering, to prevent SSRF attacks.
• 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.
