CVE-2026-15785: Joinchat cross-site scripting via {HREF}

Q: Is CVE-2026-15785 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

Q: Which versions are affected by CVE-2026-15785?

Joinchat – Enhanced “click to chat”: through 6.3.1.

Summary

Joinchat, a WordPress "click to chat" plugin, has a reflected cross-site scripting flaw in its handling of the {HREF} dynamic variable. An unauthenticated attacker can reach it remotely by tricking a user into clicking a crafted link, which then runs injected scripts in the affected page, but only if an administrator has set a phone number and used {HREF} in the call-to-action text.

Read the original description

The Joinchat – Enhanced "click to chat" plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via '{HREF}' Dynamic Variable via Query Parameter Name in all versions up to, and including, 6.3.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploitation requires that an administrator has configured a telephone number and included the {HREF} dynamic variable in the Call-to-Action text.

Check your systems with an agent

Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.

Check whether my systems are affected by CVE-2026-15785 (Joinchat <= 6.3.1 - Reflected Cross-Site Scripting via '{HREF}' Dynamic Variable), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-15785 (entry last updated 2026-11-11):
Affected:
- creapuntome Joinchat – Enhanced “click to chat”: through 6.3.1
Fixed versions: none listed yet.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-15785 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-15785 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
