The flaw allows an authenticated attacker to supply path\u2011traversal sequences in the nfsen parameter, causing the application to include arbitrary PHP files from the server filesystem. Including an arbitrary PHP file could expose sensitive configuration data or other information stored on the host. The weakness is characterized by CWE-22 and CWE-98.", "risk_and_exploitability": "The exploit requires valid credentials to allow a user to submit the nfsen parameter. The vulnerability is an LFI that does not require elevated privileges or kernel level access, making it relatively straightforward for an attacker with access. The CVSS score is 6.5 and the EPSS score is less than 1%, indicating a moderate severity with low probability of exploitation; the vulnerability is not listed in the CISA KEV catalog. The likely attack vector is an authenticated web request that manipulates the nfsen parameter with path\u2011traversal sequences. Based on the description, it is inferred that the attacker could read or include sensitive files, though concrete execution impact is not confirmed in the payload."}}}}, "created": "2026-04-14T16:16:52.599788+00:00", "updated": "2026-04-17T09:00:10.969876+00:00", "vendors": ["librenms", "librenms$PRODUCT$librenms"]}
