CVE-2026-9261
CWE-327Published: June 16, 2026· Updated: Jun 18, 2026
Official Description
Use of weak SSH cryptographic algorithms in Canon EOS Network Setting Tool Version 1.5.0 or earlier
Risk Analysis
This critical vulnerability in Canon EOS Network Setting Tool allows for the use of weak SSH cryptographic algorithms. With a CVSS score of 9.8, this flaw can lead to the compromise of sensitive information and system integrity.
No public exploit is currently known for this vulnerability. The flaw is remotely exploitable with low attack complexity, meaning an attacker can exploit it over a network without significant effort.
To mitigate this risk, update Canon EOS Network Setting Tool to a version beyond 1.5.0. Ensure that only strong, modern cryptographic algorithms are used for SSH connections.
Technical Analysis
CVE-2026-9261 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
