GetPaid WordPress plugin: Payment bypass via fractional item quantity
Summary
The GetPaid WordPress plugin does not enforce whole-number item quantities on its payment forms and buy-now buttons. An unauthenticated attacker can submit a fractional quantity so that an invoice for a priced item is marked as paid without the corresponding charge. The flaw only matters on sites where a public payment form or buy button is live.
Affected
- GetPaid WordPress plugin (invoicing) 2.8.63 and 2.8.64
- CNA range: from 2.8.63 before 2.8.65; versions before 2.8.63 are covered by a separate issue (CVE-2026-119749)
Fixed in
- Fixed in GetPaid 2.8.65 (vendor release notes, GitHub release 2.8.65)
Workaround
- No vendor workaround found. Upgrading to 2.8.65 is the fix.
- Interim measure (analyst suggestion, not from the vendor): review invoices marked as paid that have no matching gateway transaction, and check public forms for fractional quantities in order logs.
Exploitation
- Not listed in CISA KEV; CISA SSVC: exploitation none, automatable yes, technical impact partial.
- No public proof-of-concept or exploit code found so far (as of 10 Nov 2026). This is not proof that none exists.
Our recommendation
- Identify every site running GetPaid.
- Update sites on 2.8.63 or 2.8.64, and any older version, to 2.8.65 as soon as possible.
- Verify the installed version in the WordPress admin, because the wordpress.org listing may lag.
- Review recent paid invoices on sites with public payment forms or buy buttons.
- Note: the CVSS score (5.3) does not capture the business risk of unpaid goods or services being delivered.
