    CVE-2026-63198 (GCVE-0-2026-63198)

    Title
    traQ: Privilege escalation by OAuth prompt=none request
    Summary
    traQ is a messenger application built for Digital Creators Club traP. Prior to 3.28.3, OAuth2 silent authorization requests using prompt=none with an empty or omitted scope parameter check prior consent against the empty requested scope set even though all scopes registered for the client become eligible for issuance. An attacker who controls an OAuth client capable of receiving authorization codes can target a user who previously consented to only some client scopes and obtain an access token containing broader registered scopes without additional consent. A user who has never consented to the client still receives consent_required. This issue is fixed in version 3.28.3.

    Title
    traQ: XSS in the User Uploaded File Retrieval API
    Summary
    traQ is a messenger application built for Digital Creators Club traP. Prior to 3.28.3, instances configured with TRAQ_STORAGE_TYPE=local can return user-uploaded SVG or HTML content from the /files/{fileId} retrieval endpoint for direct browser rendering. An attacker with file-upload capability can provide crafted active content and induce another user to open its file URL, causing attacker-controlled JavaScript to execute in the victim's browser. This issue is fixed in version 3.28.3.

    Title
    Insertion of Sensitive Information into Log File in github.com/traPtitech/traQ
    Summary
    traQ is a messenger application built for Digital Creators Club traP. Prior to version 3.25.0, a vulnerability exists where sensitive information, such as OAuth tokens, are recorded in log files when an error occurs during the execution of an SQL query. An attacker could intentionally trigger an SQL error by methods such as placing a high load on the database. This could allow an attacker who has the authority to view the log files to illicitly acquire the recorded sensitive information. This vulnerability has been patched in version 3.25.0. If upgrading is not possible, a temporary workaround involves reviewing access permissions for SQL error logs and strictly limiting access to prevent unauthorized users from viewing them.
