Threats affecting pkg:github/abelche/cola_dnslog

CVE-2025-57403 is a high-severity directory traversal vulnerability in Cola Dnslog v1.3.2. The flaw arises when processing DNS TXT record queries, where user-supplied URL components are concatenated with a base path using os.path.join without proper sanitization. This allows attackers to perform directory traversal or absolute path injection, potentially exposing sensitive files on the server. The vulnerability requires no authentication or user interaction and can be exploited remotely over the network. Although no known exploits are currently reported in the wild, the impact on confidentiality is significant. European organizations using Cola Dnslog for DNS logging or monitoring should prioritize patching or mitigating this issue.
