Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A Stored XSS vulnerability in Roundcube Webmail. ๐ **Consequences**: Attackers can inject malicious scripts via SVG `animate` tags. This leads to session hijacking, credential theft, or defacement.โฆ
๐ก๏ธ **Root Cause**: **CWE-79** (Improper Neutralization of Input). The flaw lies in how Roundcube handles SVG documents. Specifically, the `animate` tag is not properly sanitized, allowing script injection.โฆ
๐ฆ **Affected**: Roundcube Webmail. ๐ **Versions**: < 1.5.12 AND < 1.6.12. If you are running any version prior to these releases, you are vulnerable. Check your version number immediately!
Q4What can hackers do? (Privileges/Data)
๐ **Attacker Capabilities**: Execute arbitrary JavaScript in the victim's browser. ๐ฏ **Impact**: Steal cookies/sessions, redirect users, or phish credentials.โฆ
๐ **Public Exploits**: YES. Two PoCs are available on GitHub: 1. `rxerium/CVE-2025-68461` (Detection). 2. `gotr00t0day/CVE-2025-68461` (C++ Scanner). Wild exploitation is likely imminent given the low barrier.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Use the provided GitHub scanners. Run the C++ tool against your Roundcube instance. Alternatively, inspect network traffic for unsanitized SVG `animate` tags containing script payloads.โฆ
โ **Official Fix**: YES. Patched in **1.5.12** and **1.6.12**. ๐ **Reference**: See the official Roundcube security news from Dec 13, 2025. Upgrade immediately to these versions or later.
Q9What if no patch? (Workaround)
๐ **No Patch?**: Isolate the instance. Block external access if possible. Implement WAF rules to filter SVG `animate` tags with script content. Monitor logs for XSS attempts. But upgrading is the ONLY real fix.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **HIGH**. CVSS Score indicates Critical/Sensitive impact (S:C, C:L, I:L). Public PoCs exist. No auth needed. Patch immediately. Do not wait. Your users' data is at risk.
