Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature such that the autoupdate system does not fully validate code signatures. An attacker could modify the downloaded nbm and include additional code.

Alternative Mitigation:

  • install only plugins from trusted sources and validate the downloads by checking signatures and/or comparing checksums from trusted sources
  • update to NetBeans 11.3 by downloading the release, verifying the signature and manually installing it
