CVE-2026-73433: Software Security Vulnerability Vulnerability
MODERATECVE-2026-73433 is a MODERATE (CVSS 6.6) security vulnerability vulnerability (CWE-191: Integer Underflow (Wrap or Wraparound)) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.. Remediation is available in the latest vendor maintenance releases.
CVE-2026-73433 at a Glance
Security Impact
CVSS: 6.6
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H).
How to Fix CVE-2026-73433
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree
How to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-73433, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree
Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-191: Integer Underflow (Wrap or Wraparound), where the product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result. In Software, software state validation or input boundaries are circumvented during processing.

"details" : "A flaw was found in GStreamer gst-plugins-good (avidemux). When parsing FUJIFILM metadata in an AVI strd chunk, gst_avi_demux_parse_strd() decrements a remaining-length counter by fixed offsets (98 and 10 bytes) without verifying sufficient data remains. For crafted strd payloads of exactly 106 or 107 bytes, the counter underflows to a very large unsigned value, causing subsequent null-terminated string scanning to read far beyond the allocated heap buffer. Date-format normalization may also write beyond the buffer end. Confirmed impacts include heap out-of-bounds read, out-of-bounds write, heap information disclosure (adjacent data appearing in parsed metadata), and application crash/denial of service. The avidemux element is auto-plugged by playbin, decodebin, and gst-discoverer, so opening or previewing a crafted AVI is sufficient to trigger the issue. Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072).",
