semantic-release: Exposure of Sensitive Information to an Unauthorized Actor
CVE-2022-31051 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in semantic-release, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected semantic-release versions: >= 17.0.4, < 19.0.3. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.8% chance of exploitation within 30 days, higher than 79% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of semantic-release you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions

Official description
semantic-release is an open source npm package for automated version management and package publishing. In affected versions secrets that would normally be masked by semantic-release can be accidentally disclosed if they contain characters that are excluded from uri encoding by `encodeURI`. Occurrence is further limited to execution contexts where push access to the related repository is not available without modifying the repository url to inject credentials. Users are advised to upgrade. Users unable to upgrade should ensure that secrets that do not contain characters that are excluded from encoding with `encodeURI` when included in a URL are already masked properly.

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.
