CVE-2026-115262: Duplicator < 5.1.0 - Subscriber+ SQLi via Charset and Collation Rewriter During Restore

MediumCVSS 4.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 19/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
  • Fixed version: Unknown Duplicator 5.1.0; Unknown duplicator-pro 5.1.0.

Low priority for now. Upgrade to Unknown Duplicator 5.1.0; Unknown duplicator-pro 5.1.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The Duplicator WordPress plugin before 5.1.0, duplicator-pro WordPress plugin before 5.1.0 does not restrict its database charset and collation rewrite to schema statements during a restore, so a value a Subscriber stores in their own profile can break out of its string literal and inject SQL into the restore's INSERT statement when an administrator restores the backup onto a server lacking one of the source's charsets or collations.
