CVE-2026-31309: n/a
CVE-2026-31309 is a vulnerability in Mysterium Node versions prior to 1.36.0 where improper authorization in the /tequilapi/config/user endpoint allows unauthenticated attackers to overwrite the node's configuration. This can lead to a full takeover of the node by sending a crafted POST request. No official patch or remediation level is currently confirmed. The vulnerability affects all versions before 1.36.0.
AI Analysis
Technical Summary
The vulnerability CVE-2026-31309 affects Mysterium Node before version 1.36.0. It arises from improper authorization checks on the /tequilapi/config/user endpoint, enabling unauthenticated attackers to arbitrarily overwrite the node's configuration. Exploitation requires sending a crafted POST request to this endpoint, potentially resulting in full node takeover. There is no CVSS score or vendor advisory specifying a patch or mitigation status at this time.
Potential Impact
An unauthenticated attacker can overwrite the configuration of the Mysterium Node, which may lead to complete control over the node. This compromises the integrity and availability of the node and potentially the network it participates in. No known exploits in the wild have been reported so far.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the /tequilapi/config/user endpoint and monitor for suspicious POST requests targeting this endpoint.
