Vik Rent Items (com_vikrentitems) below 1.8.7 - Missing CSRF and Access Checks, Output Escaping

Vik Rent Items 1.8.7 is a security release. E4J's changelog says it adds "various escaping, CSRF and capability checks" and "various fixes and security improvements", meaning earlier versions are missing CSRF token checks and permission checks on some tasks and print some values without escaping. It also introduces a new format for the order SID, the value that identifies a rental order in front-end links. E4J have not said which tasks were affected, and the matching WordPress release of the same codebase, which mySites.guru normally diffs to find out, has not been published yet. No CVE; severity is mySites.guru's own assessment, in line with the Vik Booking and Vik Rent Car releases that shipped the same kind of fixes. Update to 1.8.7 or later.

Affected versions: < 1.8.7

Vik Rent Items (com_vikrentitems) below 1.8.6 - Stored XSS via Custom Fields

Vik Rent Items before 1.8.6 printed custom-field names and popup-link URLs unescaped on the front-end order confirmation page (stored XSS; the fields are set by an administrator). 1.8.6 (26 Oct 2026) also adds an authorisation check to a helper and removes a debug switch. E4J publish no Joomla changelog; this is taken from the same-day WordPress release (1.2.7) of the same codebase. No CVE; severity is mySites.guru's own assessment.

Affected versions: < 1.8.6
