CERT Polska coordinated disclosure of two vulnerabilities in Asseco InfoMedica Plus, a healthcare management platform handling administrative and medical tasks. CVE-2025-8306 allows low-privileged users to obtain encoded passwords of other accounts, including the main administrator, due to inadequate access control granularity. CVE-2025-8307 involves passwords stored in an encoded rather than hashed format, with the decoding algorithm embedded in client-side software.
When chained together, these vulnerabilities enable an authenticated attacker with low privileges to escalate to administrator access. The attacker first leverages CVE-2025-8306 to extract encoded passwords from the database, then uses the client-side algorithm (CVE-2025-8307) to decode them in plaintext. Both vulnerabilities have been patched in versions 4.50.1 and 5.38.0.
The disclosure was handled through CERT Polska's coordinated vulnerability disclosure process, with credit to researcher Maciej Kazulak for responsible reporting. Healthcare organizations using Asseco InfoMedica Plus should prioritize patching to these fixed versions.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,445 reports from 149 sources, 666 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
