The Kaltura HTML5 player (mwEmbed / html5lib) contains a local file disclosure vulnerability due to improper validation of the ServiceUrl parameter in mwEmbedLoader.php. This parameter is used as the base URL for a backend request and accepts non‑HTTP schemes such as file://. When an exception or error occurs, the response is subsequently deserialized and its raw contents are reflected to the client in an error message; this enables an unauthenticated, remote attacker to read any arbitrary internal file reachable by the server. Affected versions include html5lib v2.45, v2.103 and earlier, and other v2.x releases exposing the vulnerable endpoint.
AnalysisAI
Local file disclosure in the Kaltura HTML5 player's mwEmbedLoader.php endpoint allows unauthenticated remote attackers to read arbitrary files from the server's filesystem. The root cause is that the ServiceUrl parameter - used as a base URL for backend requests - accepts non-HTTP URI schemes including file://, which the server then fetches; when an exception is raised, the raw deserialized response is reflected back to the client in the error message, leaking file contents. …

Vulnerability AssessmentAI
| Exploitation | The mwEmbedLoader.php script must be reachable by the attacker over the network - this is the primary limiting condition. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) accurately reflects the technical severity: the attack is fully remote, requires no authentication, involves no user interaction, and yields high-confidence file disclosure. … 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 | No specific patched version number is confirmed in the available intelligence data; organizations should consult the CERT/CC advisory at https://kb.cert.org/vuls/id/308749 for vendor-issued patch availability and exact fix versions. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all instances of Kaltura HTML5 player in your environment and confirm versions (html5lib v2.45, v2.103, or earlier v2.x); immediately restrict network access to the mwEmbedLoader.php endpoint via firewall rules or WAF configuration to only authorized internal systems if needed. …
