Status: AnalyzedCritical (9.8)⚠ Active exploitation💥 Exploit

PlaySMS before 1.4.3 does not sanitize inputs from a malicious string.

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Base score: 9.8

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 87%
Percentile among all scored CVEs: 100
Score date: 10/7/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

CISA KEV — actively exploited

Added to catalog: 11/3/2021
Remediation due date: 5/3/2022
Known ransomware use: Unknown

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

Metasploit module (reliable, widely available exploit) · PlaySMS index.php Unauthenticated Template Injection Code Execution
Published on Exploit-DB · PlaySMS - index.php Unauthenticated Template Injection Code Execution (Metasploit) (4/16/2020)
Nuclei template (automated mass detection) · playSMS <1.4.3 - Remote Code Execution
