Malicious release of cline (2.3.0)

OSV.dev lists one release of cline as malicious (MAL-2026-1380). The current release is not one of them.

What the advisory says

• MAL-2026-1380 lists version 2.3.0 as containing malicious code.
• The release an agent would install today is not listed.

In the AptLynx catalogue

• cline

What to do

• If a computer installed or ran an affected version, treat it as compromised, as GitHub's advisories advise: from a different computer, change every password, key and token it held, then remove the package. Removing it alone may not remove what it installed.
• Before an agent installs a package, check it: check_tools over MCP at https://aptlynx.net/mcp, or https://aptlynx.net/v1/check?item=npm:<name>.
