Container suse manager 5.0: Improper Neutralization of Script-Related HTML Tags in a Web Page
CVE-2025-53883 is a critical-severity improper neutralization of script-related HTML tags in a web page vulnerability in Container suse manager 5.0 from SUSE, with a CVSS 4.0 base score of 9.3 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 5.0.28-150600.3.36.8 as the first without the flaw, so updating Container suse manager 5.0 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.29% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Container suse manager 5.0 to 5.0.28-150600.3.36.8 or a later version.
- Update SUSE Manager Server LTS 4.3 to 4.3.88-150400.3.113.5 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Improper Neutralization of Script-Related HTML Tags in a Web Page
The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as <, >, and & that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.
How developers prevent this class of flaw
- With Struts, write all data from form beans with the bean's filter attribute set to true.
