    CVE-2026-89036 (GCVE-0-2026-89036)

    Title
    Appwrite < 2.0.0 Argument Injection via providerRootDirectory Parameter
    Summary
    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.

    Title
    Appwrite Templates github-issue-bot Skips Webhook Signature Verification When the X-Hub-Signature-256 Header Is Absent
    Summary
    The github-issue-bot templates in appwrite/templates verify the GitHub webhook signature with an inverted condition. verifyWebhook in node/github-issue-bot/src/github.js and in node-typescript/github-issue-bot/src/github.ts returns "typeof signature !== 'string' || (await verify(...))", so when the X-Hub-Signature-256 header is absent the first operand is true, the logical OR short-circuits, and the function reports success without performing any HMAC verification. main.js rejects a request only when verifyWebhook returns false, so an unauthenticated request carrying no signature passes the check. Processing then continues to postComment, which takes the repository and issue objects directly from the request body, letting the caller direct the deployed function to post a comment on a repository and issue of their choosing using the configured GITHUB_TOKEN, with the issue author login from the body interpolated into the comment text.

    Vulnerability from nvd – Published: 2024-02-22 00:00 – Updated: 2024-08-21 17:46
    VLAI
    Summary
    The ACME-challenge endpoint in Appwrite 0.5.0 through 0.12.x before 0.12.2 allows remote attackers to read arbitrary local files via ../ directory traversal. In order to be vulnerable, APP_STORAGE_CERTIFICATES/.well-known/acme-challenge must exist on disk. (This pathname is automatically created if the user chooses to install Let's Encrypt certificates via Appwrite.)

    Title
    Appwrite < 2.0.0 Argument Injection via providerRootDirectory Parameter
    Summary
    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.

    Title
    Appwrite Templates github-issue-bot Skips Webhook Signature Verification When the X-Hub-Signature-256 Header Is Absent
    Summary
    The github-issue-bot templates in appwrite/templates verify the GitHub webhook signature with an inverted condition. verifyWebhook in node/github-issue-bot/src/github.js and in node-typescript/github-issue-bot/src/github.ts returns "typeof signature !== 'string' || (await verify(...))", so when the X-Hub-Signature-256 header is absent the first operand is true, the logical OR short-circuits, and the function reports success without performing any HMAC verification. main.js rejects a request only when verifyWebhook returns false, so an unauthenticated request carrying no signature passes the check. Processing then continues to postComment, which takes the repository and issue objects directly from the request body, letting the caller direct the deployed function to post a comment on a repository and issue of their choosing using the configured GITHUB_TOKEN, with the issue author login from the body interpolated into the comment text.

    VLAI
    Summary
    The ACME-challenge endpoint in Appwrite 0.5.0 through 0.12.x before 0.12.2 allows remote attackers to read arbitrary local files via ../ directory traversal. In order to be vulnerable, APP_STORAGE_CERTIFICATES/.well-known/acme-challenge must exist on disk. (This pathname is automatically created if the user chooses to install Let's Encrypt certificates via Appwrite.)
