attackers to cookies that may have been injected into the log file if the site administrator triggered a back-up using a specific user role like 'administrator.'

Mitigating Controls (NIST 800-53 r5)AI

AC-22 Publicly Accessible Content good match
prevent

Directly requires organizations to review, restrict, and protect publicly accessible content to prevent exposure of sensitive authentication cookies in files like cookies.txt.

IA-5 Authenticator Management good match
prevent

Mandates protection of authenticators such as authentication cookies from unauthorized disclosure and use by unauthenticated attackers.

SI-2 Flaw Remediation good match
prevent

Requires timely identification, reporting, and remediation of flaws like the plugin vulnerability that leads to public exposure of authentication cookies.

Security SummaryAI

CVE-2025-11693 is a sensitive information exposure vulnerability (CWE-200) affecting the Export WP Page to Static HTML & PDF plugin for WordPress in all versions up to and including 4.3.4. The issue arises from publicly exposed cookies.txt files that contain authentication cookies, which can be accessed due to improper handling during backup processes.

Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no privileges required (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, score 9.8). Exploitation occurs if a site administrator triggers a backup using a specific user role like administrator, injecting authentication cookies into the publicly accessible log file, allowing attackers to retrieve them and potentially gain unauthorized access or perform further actions.

Advisories reference a WordPress plugin trac changeset (3388166) indicating a patch, and a Wordfence threat intelligence report (ID cd28ac3c-aaef-49e3-843d-8532404703c9) detailing the vulnerability. Security practitioners should update to a patched version beyond 4.3.4 and review exposed files for remediation.
