CVE-2025-68279 is a path traversal vulnerability identified in the Weblate localization tool prior to version 5.15.1. Weblate is a web-based platform used for software localization management, which integrates with version control repositories. The vulnerability arises due to improper limitation of pathnames when handling symbolic links within repositories. Specifically, crafted symbolic links can be used to traverse outside the intended directory boundaries, allowing an attacker to read arbitrary files on the server's filesystem. This flaw is categorized under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), CWE-59 (Improper Link Resolution), and CWE-200 (Exposure of Sensitive Information). The CVSS v3.1 score is 7.7 (high), reflecting that the vulnerability can be exploited remotely over the network (AV:N) with low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N). The scope is changed (S:C), and the impact is high on confidentiality (C:H), with no impact on integrity or availability. The vulnerability allows an attacker with limited privileges to read sensitive files such as configuration files, credentials, or other private data stored on the server, potentially leading to further attacks or data breaches. The issue was resolved in Weblate version 5.15.1 by properly restricting pathname resolution and handling of symbolic links to prevent directory traversal. No known exploits have been reported in the wild as of the publication date.

For European organizations, the impact of this vulnerability is significant, particularly for those relying on Weblate for localization and software development workflows. Unauthorized reading of arbitrary files can lead to exposure of sensitive information such as source code, credentials, internal documentation, or personally identifiable information (PII). This can facilitate further attacks like privilege escalation, lateral movement, or targeted data theft. Organizations in sectors such as technology, finance, government, and telecommunications, which often use localization tools, may face regulatory and reputational damage if sensitive data is leaked. Additionally, the breach of confidentiality could violate GDPR requirements, leading to legal and financial penalties. Since the vulnerability requires some level of privileges, insider threats or compromised accounts could exploit it remotely, increasing risk in multi-tenant or cloud-hosted environments common in Europe.

The primary mitigation is to upgrade Weblate installations to version 5.15.1 or later, where the vulnerability is fixed. Organizations should audit their repositories for the presence of malicious or unexpected symbolic links that could be exploited. Implement strict access controls and monitoring on Weblate servers to limit the privileges of users and services interacting with repositories. Employ file integrity monitoring to detect unauthorized changes or suspicious symlink creations. Network segmentation and firewall rules should restrict access to Weblate management interfaces to trusted personnel only. Additionally, conduct regular security assessments and penetration testing focused on repository handling and symbolic link resolution. Educate developers and administrators about the risks of path traversal and secure repository management practices. Finally, maintain up-to-date backups and incident response plans to quickly recover from potential data exposure incidents.
