CVE-2026-32712: Open Source Point of Sale has Stored XSS in Customer Name (Sales)

Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 0.17% (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. No special conditions are required; it is repeatable.
  • Fixed version: opensourcepos opensourcepos 3.4.3.

Low priority for now. Upgrade to opensourcepos opensourcepos 3.4.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Open Source Point of Sale is a web based point-of-sale application written in PHP using CodeIgniter framework. Prior to 3.4.3, a Stored Cross-Site Scripting (XSS) vulnerability exists in the Daily Sales management table. The customer_name column is configured with escape: false in the bootstrap-table column configuration, causing customer names to be rendered as raw HTML. An attacker with customer management permissions can inject arbitrary JavaScript into a customer's first_name or last_name field, which executes in the browser of any user viewing the Daily Sales page. This vulnerability is fixed in 3.4.3.
