Detailsinfo

A vulnerability was found in Softaculous Backuply Plugin up to 1.5.8 and classified as critical. Affected by this issue is some unknown functionality of the component Restore. The manipulation of the argument Biographical Info with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The Backuply – Backup, Restore, Migrate and Clone plugin for WordPress is vulnerable to SQL Injection via the Biographical Info field (second-order, via restore) in all versions up to, and including, 1.5.8 due to insufficient escaping on the user supplied parameter and the lack of sufficient preparation on an existing SQL query. Backuply exports the Biographical Info value verbatim inside an INSERT statement written to the backup's SQL dump (wp_usermeta). When an Administrator later restores such a backup, the crafted payload breaks out of that INSERT statement and appends attacker-controlled SQL that executes with full database privileges. This makes it possible for authenticated attackers, with subscriber-level access and above, to write arbitrary data to the database — in particular to update the default_role option in wp_options to administrator (and enable open user registration) — so that a subsequently registered account is automatically granted the Administrator role, resulting in privilege escalation and full site takeover. Because the injection executes inside an INSERT during restore with no response returned to the attacker, the primitive is used to modify database records rather than to read existing data directly.

The advisory is shared for download at wordfence.com. This vulnerability is handled as CVE-2026-93953 since 09/19/2026. The exploitation is known to be easy. The attack may be launched remotely. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 10/16/2026). The MITRE ATT&CK project declares the attack technique as T1505.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
