Routine

LOW 3.7REMOTEUPGRADE

CVE-2020-15262 is a low-severity flaw (CVSS 3.7) affecting webpack-subresource-integrity. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In webpack-subresource-integrity before version 1.5.1, all dynamically loaded chunks receive an invalid integrity hash that is ignored by the browser, and therefore the browser cannot validate their integrity. This removes the additional level of protection offered by SRI for such chunks. Top-level chunks are unaffected. This issue is patched in version 1.5.1.

Why this priority

Remotely exploitable, no login, no user action

A fixed release or distro patch exists.
