Vulnerability in Drupal Lunr exposed filters. This issue affects Lunr exposed filters versions: *.*.
AnalysisAI
Improper input validation in the Drupal Lunr Exposed Filters contributed module (all versions) can yield high confidentiality and integrity impact under a restrictive set of preconditions. The CVSS vector (AV:N/AC:H/PR:H/UI:R) constrains exploitation to attackers already holding high-privilege Drupal access who can also induce user interaction, making opportunistic or mass exploitation implausible. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires all of the following conditions simultaneously: the Drupal Lunr Exposed Filters module must be installed and enabled on the target site (all versions *.*); the attacker must already possess high-privilege access to the Drupal application (PR:H - consistent with administrator or equivalent role); the attack path involves high complexity (AC:H), indicating a non-trivial, multi-step approach rather than a simple request; and user interaction (UI:R) from another party must be induced to trigger the vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The published CVSS 5.7 score and C:H/I:H impact components appear alarming in isolation, but the four concurrent exploitation constraints - AC:H (high complexity), PR:H (high privileges), UI:R (user interaction required), and S:U (no scope change) - collectively represent a very narrow attack surface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Administrators should immediately consult the Drupal Security Advisory at https://www.drupal.org/sa-contrib-2026-086 for the specific patched module version and apply it via Drupal's standard update pathway (drush up or the admin UI update manager). … Detailed patch versions, workarounds, and compensating controls in full report. |
