CVE-2026-56096: Information Disclosure in extension "Apache Solr for TYPO3 - Enterprise Search" (solr)

Noroxi assessment

Priority: Monitor (action score 25/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.42% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: TYPO3 Extension "Apache Solr for TYPO3 - Enterprise Search" 11.2.8, 11.6.6, 12.1.4.

Low priority for now. Upgrade to TYPO3 Extension "Apache Solr for TYPO3 - Enterprise Search" 11.2.8, 11.6.6, 12.1.4 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

The extension passes the user-supplied search query parameter to Apache Solr without restricting advanced Solr query syntax such as wildcards, field selectors and range queries. A remote, unauthenticated attacker can use this syntax to enumerate indexed field names and extract their stored values through boolean- and range-based blind extraction techniques, independent of any site-specific configuration.
