WPvivid — Backup, Migration & Staging: Exposure of Sensitive Information to an Unauthorized Actor
CVE-2023-5576 is a critical-severity exposure of sensitive information to an unauthorized actor vulnerability in WPvivid — Backup, Migration & Staging from Wpvividplugins, with a CVSS 3.1 base score of 9.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected WPvivid — Backup, Migration & Staging versions: 0.9.91 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.89% chance of exploitation within 30 days, higher than 60% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of WPvivid — Backup, Migration & Staging you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
The Migration, Backup, Staging - WPvivid plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 0.9.91 via Google Drive API secrets stored in plaintext in the publicly visible plugin source. This could allow unauthenticated attackers to impersonate the WPVivid Google Drive account via the API if they can trick a user into reauthenticating via another vulnerability or social engineering.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How developers prevent this class of flaw
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
