Summary

CVE-2025-26886 is a high-severity SQL Injection (CWE-89) vulnerability. Its CVSS base score is 7.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 18.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2025-26886 is an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability, classified under CWE-89, in the PublishPress Authors WordPress plugin (publishpress-authors). This issue affects all versions of the plugin from n/a through 4.7.3 inclusive. The vulnerability was published on 2025-03-15 and carries a CVSS v3.1 base score of 7.6.

Exploitation is possible over the network (AV:N) with low attack complexity (AC:L), requiring high privileges (PR:H) but no user interaction (UI:N). The changed scope (S:C) enables high confidentiality impact (C:H), no integrity impact (I:N), and low availability impact (A:L), potentially allowing privileged attackers to extract sensitive data from the database.

Mitigation details are available in the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/publishpress-authors/vulnerability/wordpress-publishpress-authors-plugin-4-7-3-sql-injection-vulnerability?_s_id=cve.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly addresses SQL injection by requiring validation and sanitization of user inputs before incorporation into SQL commands in the PublishPress Authors plugin.

SI-2 Flaw Remediation good match
prevent

Mandates timely identification, reporting, and remediation of the known SQL injection flaw affecting PublishPress Authors versions through 4.7.3.

AC-6 Least Privilege partial match
prevent

Enforces least privilege to restrict exploitation to only necessary high-privileged users, reducing the attack surface for this PR:H SQL injection vulnerability.
