SP Property Finder (com_spproperty) below 4.1.4 - Unauthenticated SQL Injection (full database read) and Mail Relay

SP Property Finder below 4.1.4 contains an unauthenticated blind SQL injection in the public property search and map views, found by mySites.guru and reported privately to JoomShaper on 10 August 2026. Several search filters (the postcode, the sort control, and the price and size range dropdowns) are placed straight into the database query with no quoting, so an anonymous visitor with no login and no token can read any table in the Joomla database, password hashes and the site secret included. The injection is read-only, but reading the session table lets an attacker steal a logged-in administrator's session and take over the site from there, so treat it as serious. A second, lower-severity issue let the property contact and enquiry forms send email to any recipient with a spoofed sender (an unauthenticated mail relay). JoomShaper fixed both in SP Property Finder 4.1.4, released on 10 September 2026, which quotes and casts every filter value, validates the sort control against an allow-list, and derives the mail recipient from a database lookup instead of the request. mySites.guru verified the fix against the build JoomShaper shipped as 4.1.4. The same release also fixed further issues that mySites.guru did not report, tracked as CVE-2026-78084, CVE-2026-78302 and CVE-2026-78303. The reporter's two findings are CVE-2026-78082 (the SQL injection, published by the Joomla CNA at 9.3 Critical and credited to Phil Taylor of mySites.guru) and CVE-2026-78303 (the mail relay). The release also fixed CVE-2026-78083, CVE-2026-78084 and CVE-2026-78302, which mySites.guru did not report. All five CVE records were published at MITRE on 10 September 2026. Update to SP Property Finder 4.1.4 or later from JoomShaper. Updating closes the flaw but does not undo any database read that already happened: if a vulnerable version was public for a while, treat the password hashes and the site secret as potentially known.
