CVE-2022-44311

Status: ModifiedHigh (8.1)—💥 PoC

html2xhtml v1.3 was discovered to contain an Out-Of-Bounds read in the function static void elm_close(tree_node_t *nodo) at procesador.c. This vulnerability allows attackers to access sensitive files or cause a Denial of Service (DoS) via a crafted html file.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
