CVE-2026-26284

The pcd coder lacks proper boundary checking when processing Huffman-coded data. The decoder contains an function that has an incorrect initialization that could cause an out of bounds read.

==3900053==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x502000003c6c at pc 0x55601b9cc552 bp 0x7ffd904b1f70 sp 0x7ffd904b1f60
READ of size 1 at 0x502000003c6c thread T0

A read operation accesses a memory location beyond the intended buffer boundary. Typical impact: sensitive data disclosure or crash.

CVE-2026-26284 has a CVSS score of 6.5 (Medium). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (14.10.3); upgrading removes the vulnerable code path.

4. Is there a fix for CVE-2026-26284? Yes. CVE-2026-26284 is fixed in 14.10.3. Upgrade to this version or later.
5. Is CVE-2026-26284 exploitable, and should I be worried? Whether CVE-2026-26284 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-26284 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
