Malicious code in eslint-plugin-i18n-shreddit (npm)

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

--- _-= Per source details.

Package metadata is characteristic of a dependency-confusion probe: version 99.9.9 (chosen to win resolution against a lower-versioned internal package of the same name), empty description, empty author, and no exported plugin functionality. Installing this package leaks the installer's identifiers and network position to an attacker-controlled webhook, identifying vulnerable internal build environments for follow-on targeting.
