A flaw has been found in olivier-ls PHP-FTS up to 1.1.2. Affected by this issue is the function SearchEngine::buildHighlights of the file src/SearchEngine.php of the component Search Engine. Executing a manipulation of the argument Query can lead to cross site scripting. The attack may be launched remotely. The exploit has been published and may be used. Upgrading to version 1.1.3 can resolve this issue. This patch is called 0b2fae333d6b022da7ed4c43e2d41aa03f91dff3. The affected component should be upgraded. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.
AnalysisAI
Stored cross-site scripting in the PHP-FTS full-text search library (olivier-ls/php-fts) through version 1.1.2 lets an attacker who can introduce content into the search index inject markup that executes in a victim's browser when the application renders the returned search highlights as HTML. The flaw sits in SearchEngine::buildHighlights in src/SearchEngine.php, which concatenates stored field text with opening and closing highlight tags without escaping it; per the vendor's own CVSS:4.0 vector the attacker is an authenticated remote user (PR:L) and exploitation requires the victim to interact (UI:P), with impact limited to manipulated content (VI:L) and no confidentiality or availability loss. …

Vulnerability AssessmentAI
| Exploitation | Exploitable only when a host application (1) indexes attacker-influenceable/user-supplied content with PHP-FTS ≤1.1.2, and (2) renders the returned 'highlights' output as HTML rather than escaping it downstream. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely low-priority issue despite being a real, confirmed vulnerability. … 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 | Upgrade PHP-FTS to version 1.1.3 or later, which is the vendor-released patch applying commit 0b2fae333d6b022da7ed4c43e2d41aa03f91dff3 (available via the project repository and packagist tags at https://github.com/olivier-ls/php-fts/tags). … Detailed patch versions, workarounds, and compensating controls in full report. |
