CVE-2026-108770
MediumCVSS 5.3Summary
A weakness has been identified in Appwrite up to 2.3.0. The function PublicHostname of the file src/Appwrite/Platform/Modules/Avatars/Http/Screenshots/Get.php in the Browser Screenshot Service component is affected. Manipulation of the argument url causes server-side request forgery. The attack can be initiated remotely. Upgrading to version 2.4.0 resolves the issue.

An attacker can exploit SSRF to make requests to internal network resources, potentially leading to disclosure of sensitive information or attacks on internal services.
Recommendation

See all- CVE-2023-27159High

- CVE-2026-89036High
Appwrite before 2.0.0 contains an argument injection vulnerability that allows authenticated users with functions.write or sites.write permissions to execute arbitrary commands by injecting TAB characters into the providerRootDirectory parameter used to construct GNU tar commands. The application uses escapeshellcmd instead of escapeshellarg and fails to quote the parameter, allowing TAB characters to survive sanitization and be interpreted as argument separators, enabling injection of arbitrary GNU tar arguments such as --checkpoint-action=exec to achieve remote code execution as the builds worker process user.
