CVE-2023-50931
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in savignano S/Notify before 2.0.1 for Bitbucket. While an administrative user is logged on, the configuration settings of S/Notify can be modified via a CSRF attack. The injection could be initiated by the administrator clicking a malicious link in an email or by visiting a malicious website. If executed while an administrator is logged on to Bitbucket, an attacker could exploit this to modify the configuration of the S/Notify app on that host. This can, in particular, lead to email notifications being no longer encrypted when they should be.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceS/Notify plugin for Bitbucket versions before 2.0.1 lack anti-CSRF tokens on configuration endpoints, allowing attackers to craft malicious requests that modify plugin settings (including email encryption settings) when an administrator is logged in and visits a malicious site.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify S/Notify plugin is installedIn Bitbucket, go to Administration > Apps > Find S/Notify or S/Notify for Bitbucket in the installed apps listAffected if S/Notify plugin appears in the installed applications
-
Check installed S/Notify versionIn Bitbucket Administration > Apps, click on S/Notify to view its details and note the version number shownAffected if Version displayed is less than 2.0.1 (for example, 2.0.0, 1.x.x, etc.)
-
Confirm plugin configuration access existsIn Bitbucket Administration, navigate to the S/Notify plugin settings section (typically under Apps or Plugins category) to confirm the configuration endpoints are accessibleAffected if Configuration panel for S/Notify is accessible to administrators
User is affected if S/Notify plugin is installed with a version less than 2.0.1 and administrators can access its configuration endpoints.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.0.1
Upgrade S/Notify to version 2.0.1 or later which includes CSRF protection. As a temporary workaround, administrative users should avoid clicking untrusted links while logged into Bitbucket.
2.0.1
- Verify current S/Notify version by accessing Bitbucket administration settings for installed apps
- Locate S/Notify in the list of installed Bitbucket apps
- Click on the update option or uninstall the current version
- Install or update to S/Notify version 2.0.1 or later
- Verify the upgrade was successful by checking the installed version in Bitbucket admin
- Log out and log back in to ensure session tokens are refreshed
