CVE-2026-110592 Details
Description
BottleCRM 0.30 through 1.14.5 contains an HTML injection vulnerability in render_invoice_template() that allows authenticated organization members to inject markup into custom-template invoice PDFs. Attackers can place HTML and CSS in notes, terms, client name or address fields to overlay totals, payee and payment instructions in PDFs served via download, public links and emails.
A vulnerability allowing HTML injection has been identified in BottleCRM versions 0.30 through 1.14.5. The issue arises in the 'render_invoice_template()' function, where authenticated organization members can inject HTML and CSS into custom invoice PDFs. This injection can be done through notes, terms, client name, or address fields, allowing attackers to overlay or manipulate key invoice details such as totals, payee information, and payment instructions. The compromised PDFs can be distributed via download, public links, or email.
It is recommended to apply HTML escaping to all user-supplied values before they are inserted into the invoice templates. This can be done using Python's built-in 'html' library, which converts special characters into their HTML entity equivalents, preventing the browser from interpreting them as HTML.
