CVE-2026-22250 is a vulnerability affecting the Weblate command-line client, known as wlc, which utilizes Weblate's REST API. This vulnerability allows SSL verification to be bypassed for certain crafted URLs. Specifically, this issue exists in all versions prior to 1.17.0, and has been addressed in version 1.17.0, making it critical for users to update their installations.
The severity of this vulnerability is classified as low, with a CVSS score of 2.5. While it may not exhibit immediate severe impacts, it poses a risk to the confidentiality of data transmitted over SSL, which can lead to potential exploitation if left unaddressed. Organizations utilizing the Weblate wlc client should incorporate this vulnerability remediation into their security patching strategy.
As of now, there are no known public exploits or proof of concepts available for this vulnerability, which suggests a lower urgency for immediate action compared to other vulnerabilities. However, organizations are advised to update to the latest version to mitigate any risks associated with SSL verification being skipped.
The publication date for this vulnerability was January 12, 2026, with the last modification on January 27, 2026. Organizations should take note of this timeframe when assessing their vulnerability management processes and schedules.
Organizations should prioritize patching immediately to safeguard their systems against potential risks arising from this vulnerability.
Vulnerability Details
The official description of CVE-2026-22250 highlights that the wlc command-line client allows SSL verification to be skipped for specially crafted URLs prior to version 1.17.0. This vulnerability is assigned to CWE-295, which relates to SSL certificate validation issues.
The vulnerability has a CVSS score of 2.5, indicating a low severity with the following characteristics: it requires a local attack vector, has a high attack complexity, requires low privileges, and necessitates user interaction.
Affected systems include all versions of wlc prior to the vendor patch of 1.17.0. The vulnerability was disclosed on January 12, 2026.
Technical Analysis
The root cause of this vulnerability is the improper handling of SSL verification within the wlc command-line client. This allows attackers to potentially intercept or manipulate data sent over SSL, creating a risk of sensitive information exposure.
The attack vector is local, meaning that an attacker would need access to the local environment where the client operates. The attack complexity is considered high, as it requires specific conditions to be met for exploitation. Additionally, low privileges are required to carry out the attack, but user interaction is necessary to trigger the vulnerable functionality.
The impact on confidentiality is low, as the vulnerability primarily affects the verification of SSL connections, while integrity and availability impacts are none.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2026-22250 is moderate. Although the base score is low, the ability to skip SSL verification can lead to potential data interception in a local environment, particularly if untrusted networks are used.
Organizations should consider the implications of this vulnerability in their operational strategies. The blast radius could be limited to the systems utilizing the affected version of the wlc client. Given the current lack of known exploits, the urgency for immediate remediation is lower, but it is advisable to address this vulnerability in the next patch cycle.
As a further precaution, organizations should regularly monitor their systems for any signs of exploitation and ensure that their incident response plans are up to date.
