Name of the Vulnerable Software and Affected Versions pnpm versions prior to 10.34.2 pnpm versions prior to 11.5.3
Description The generic peer-suffix normalizer incorrectly strips parenthesized text from git, URL, tarball, file, and other opaque locators. This behavior allows a scenario where approval for one source string could inadvertently authorize a different, attacker-controlled source that normalizes to the same value.
Recommendations Update to version 10.34.2. Update to version 11.5.3.
