CVE-2022-28276 is an out-of-bounds write vulnerability (CWE-787) affecting Adobe Photoshop versions 22.5.6 and earlier, as well as 23.2.2 and earlier. This vulnerability arises when Photoshop improperly handles memory boundaries during processing of certain input data, leading to the possibility of writing data outside the intended memory buffer. Such out-of-bounds writes can corrupt memory, potentially allowing an attacker to execute arbitrary code within the context of the current user. Exploitation requires user interaction, specifically that the victim opens a maliciously crafted file designed to trigger the vulnerability. The vulnerability does not require elevated privileges or authentication but depends on the victim's action to open the file. There are no known exploits in the wild reported to date, and no official patches or updates are linked in the provided information, indicating that mitigation may rely on updates from Adobe or other defensive measures. The vulnerability affects widely used versions of Photoshop, a popular image editing software used extensively in creative industries, marketing, media, and other sectors. Given the nature of the vulnerability, successful exploitation could lead to arbitrary code execution, enabling attackers to compromise the affected system, steal data, or deploy malware. However, the requirement for user interaction and the absence of known active exploits reduce the immediacy of the threat. The vulnerability was publicly disclosed in May 2022 and is recognized by CISA, indicating its relevance to cybersecurity stakeholders.

For European organizations, the impact of CVE-2022-28276 could be significant in sectors relying heavily on Adobe Photoshop, such as advertising agencies, media companies, design firms, and other creative industries. Successful exploitation could lead to unauthorized code execution, potentially resulting in data breaches, intellectual property theft, or deployment of ransomware and other malware. Since the vulnerability executes code with the privileges of the current user, the impact depends on the user's permissions; if the user has administrative rights, the attacker could gain full system control. The requirement for user interaction (opening a malicious file) means that phishing or social engineering campaigns could be vectors for exploitation, increasing risk in environments where users frequently exchange image files. The vulnerability could also be leveraged as an initial access vector in multi-stage attacks targeting critical infrastructure or enterprises. However, the absence of known exploits in the wild and the medium severity rating suggest that the immediate risk is moderate but should not be underestimated, especially in high-value targets or environments with lax user security awareness.

1. Apply official Adobe Photoshop updates as soon as they become available to address this vulnerability. Monitor Adobe security advisories regularly. 2. Implement strict email and file filtering to detect and block malicious files, especially those with image extensions or unusual metadata. 3. Educate users on the risks of opening unsolicited or unexpected files, emphasizing caution with files received via email or untrusted sources. 4. Employ endpoint protection solutions capable of detecting anomalous behavior or exploitation attempts related to memory corruption. 5. Use application whitelisting to restrict execution of unauthorized code and limit the impact of potential exploitation. 6. Enforce the principle of least privilege by ensuring users operate with minimal necessary permissions to reduce the potential impact of code execution. 7. Utilize sandboxing or isolated environments for opening files from untrusted sources to contain potential exploitation. 8. Monitor network and host logs for unusual activity that may indicate exploitation attempts, such as unexpected process launches or memory access violations.
