AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Network-reachable but requires an authenticated low-priv account (PR:L) and non-trivial preconditions (AC:H); confidentiality high from file disclosure, but integrity/availability only low as code execution is conditional.

PHP Local File Inclusion in the Select-Themes SetSail WordPress theme (versions up to and including 2.1) allows an authenticated attacker to coerce the application into including local files via improper control of a filename in an include/require statement. Successful exploitation can disclose sensitive files (e.g., wp-config.php) and, depending on server conditions, escalate to code execution through log poisoning or PHP wrapper abuse. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated session - the CVSS vector specifies PR:L, so a valid low-privilege WordPress account (e.g., subscriber/contributor-level access) on the target site is a prerequisite, and no user interaction is needed (UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 score is 7.5 (High) with vector AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating network reach but high attack complexity and a requirement for at least low-level privileges (PR:L, i.e., an authenticated account). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who holds a low-privileged authenticated WordPress account sends a crafted request to a SetSail theme endpoint, supplying a manipulated file/path parameter with traversal sequences to make PHP include a local file such as wp-config.php, disclosing database credentials and secret keys. If the server allows it, the attacker chains the LFI with log poisoning or a PHP wrapper to achieve code execution. … |
| Remediation | No fixed version number is provided in the available data, so no vendor-released patch version can be confirmed at time of analysis; consult the Patchstack advisory (https://patchstack.com/database/Wordpress/Theme/setsail/vulnerability/wordpress-setsail-theme-2-1-local-file-inclusion-vulnerability?_s_id=cve) and Select-Themes for an update newer than 2.1 and upgrade as soon as one is published. … Detailed patch versions, workarounds, and compensating controls in full report. |
