- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 2.1% (FIRST EPSS); higher than 82.7% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: putty (Debian:12) 0.54-1.
Low priority for now. Upgrade to putty (Debian:12) 0.54-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
The PuTTY terminal emulator 0.53 allows attackers to modify the window title via a certain character escape sequence and then insert it back to the command line in the user's terminal, e.g. when the user views a file containing the malicious sequence, which could allow the attacker to execute arbitrary commands.
