Openlist · Openlist · CVE-2026-25060
**Name of the Vulnerable Software and Affected Versions**
OpenList versions prior to 4.1.10
**Description**
The OpenList application disables TLS certificate verification by default for all outgoing storage driver communications, creating a risk of Man-in-the-Middle (MitM) attacks. This allows attackers to intercept and manipulate all storage communications, potentially leading to the decryption, theft, and manipulation of data. Attackers can leverage network-level attacks, such as ARP spoofing or compromised network equipment, to redirect traffic to malicious endpoints. The `TlsInsecureSkipVerify` setting is set to true by default in the `DefaultConfig()` function. This enables attackers to establish encrypted connections with attacker-controlled servers, allowing full decryption and manipulation of storage operations without security warnings. A proof-of-concept demonstrated successful interception of authentication cookies by redirecting traffic to a malicious HTTPS server.
**Recommendations**
Versions prior to 4.1.10: Upgrade to version 4.1.10 or later to enable certificate verification and mitigate the risk of MitM attacks.
