Weblate ≤ 5.16
Raw vector
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:LCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2026-24126 is a medium-severity Argument Injection (CWE-88) vulnerability in Weblate Weblate. Its CVSS base score is 6.6 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 37th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2026-24126 is an argument injection vulnerability in Weblate, a web-based localization tool. Prior to version 5.16.0, the SSH management console fails to validate user input when adding an SSH host key, allowing injection of arguments into the `ssh-add` command. This issue is classified under CWE-88 and carries a CVSS v3.1 base score of 6.6 (AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L).
The vulnerability can be exploited by a high-privileged user (PR:H) with network access to the Weblate instance who can interact with the SSH management console. By supplying malicious input during SSH host key addition, an attacker can inject arguments into `ssh-add`, potentially leading to arbitrary command execution within the context of the Weblate process. This results in low impacts to confidentiality, integrity, and availability, but with a changed scope (S:C) that may affect related components or the broader system.
Weblate version 5.16.0 addresses the issue through input validation in the SSH management console, as detailed in the project's security advisory (GHSA-33fm-6gp7-4p47), associated pull request (#17722), and fixing commit (78773cc141ce0a97900c11341e6cf856451395fd). As a workaround, administrators should restrict access to the management console.

Vulnerability Data
Weblate is a web based localization tool. Prior to 5.16.0, the SSH management console did not validate the passed input while adding the SSH host key, which could lead to an argument injection to `ssh-add`. Version 5.16.0 fixes the issue.…

As a workaround, properly limit access to the management console.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing can discover argument-injection flaws in command-construction code but does not stop their introduction.
Input validation directly stops construction of command strings containing unneutralized delimiters or injected arguments.

Security testing can detect argument injection but does not prevent it at the source.
Secure development lifecycle mandates input validation and command construction practices that directly prevent argument injection.
Application security requirements include explicit rules for safe command-line argument handling and escaping.
Secure architecture principles discourage unsafe command invocation patterns and favor safer APIs.
Secure coding standards explicitly require proper neutralization of command arguments, directly eliminating CWE-88.
