CVE-2020-11027: Password reset links invalidation issue in WordPress

Noroxi assessment

Priority: Monitor (action score 36/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 13.6% (FIRST EPSS); higher than 96.4% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: WordPress WordPress 5.4.1.
  • Severity is disputed: the assigning authority (CNA) scores it 6.1, NVD 8.1.

Low priority for now. Upgrade to WordPress WordPress 5.4.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In affected versions of WordPress, a password reset link emailed to a user does not expire upon changing the user password. Access would be needed to the email account of the user by a malicious party for successful execution. This has been patched in version 5.4.1, along with all the previously affected versions via a minor release (5.3.3, 5.2.6, 5.1.5, 5.0.9, 4.9.14, 4.8.13, 4.7.17, 4.6.18, 4.5.21, 4.4.22, 4.3.23, 4.2.27, 4.1.30, 4.0.30, 3.9.31, 3.8.33, 3.7.33).
