The vulnerability is a classic stable memory read error (CWE-125) that does not grant execution privileges but can reveal confidential data to the attacker. Exploitation requires the victim to open a crafted file, so it depends on user interaction rather than a network-based attack vector.", "risk_and_exploitability": "The CVSS base score of 5.5 places the vulnerability in the moderate category, yet the EPSS score of less than 1% indicates a very low likelihood of real-world exploitation. Because the flaw requires the victim to open a maliciously crafted file, it is a user-dependent attack vector. The vulnerability is not listed in CISA\u2019s KEV catalog, reducing the expectation of actively exploited instances. Nonetheless, unpatched systems remain susceptible to accidental or targeted exploitation via social engineering or malicious content distribution."}}}}, "created": "2026-01-14T11:07:54.117730+00:00", "updated": "2026-04-18T16:30:05.078010+00:00", "vendors": ["adobe", "adobe$PRODUCT$substance_3d_modeler"]}
