CVE-2022-28244: Adobe Acrobat Reader DC CSP Bypass Leads To Privilege Escalation
Acrobat Reader DC versions 22.001.20085 (and earlier), 20.005.3031x (and earlier) and 17.012.30205 (and earlier) is affected by a violation of secure design principles through bypassing the content security policy, which could result in an attacker sending arbitrarily configured requests to the cross-origin attack target domain. Exploitation requires user interaction in which the victim needs to access a crafted PDF file on an attacker's server.
Security readout for executives and security teams
Plain-English summary
This flaw lets a crafted PDF bypass Acrobat Reader DC’s content security policy and make configured cross-origin requests. A victim must interact with the malicious PDF from an attacker-controlled server. The main business risk is exposure of sensitive information from affected Reader installations, not automatic internet-scale compromise.
Executive priority
Treat this as a moderate endpoint risk requiring routine but tracked remediation. It needs user interaction and has no provided evidence of active exploitation, but the confidentiality impact is high enough to justify prompt patch verification.
Technical view
CVE-2022-28244 is a secure-design violation in Adobe Acrobat Reader DC affecting 22.001.20085 and earlier, 20.005.3031x and earlier, and 17.012.30205 and earlier. The issue enables CSP bypass and attacker-configured requests to a cross-origin target. CVSS 3.1 is 6.3 with required user interaction and high confidentiality impact.
Likely exposure
Organizations are exposed where users run affected Acrobat Reader DC versions and open untrusted PDFs, especially from external links. The provided sources do not identify server-side products, browser-only exposure, or non-Reader Adobe products as affected.
Exploitation context
The source bundle says exploitation requires the victim to access a crafted PDF on an attacker’s server. KEV is false, and the provided sources do not support a claim of active exploitation.
Researcher notes
Evidence is limited to the CVE description, CVSS data, CWE-657, and Adobe advisory reference. The bundle does not provide exploit details, detection indicators, or explicit fixed build numbers. Validate patch mapping directly against Adobe APSB22-16.
Mitigation direction
Review Adobe APSB22-16 for official fixed versions and update guidance.
Upgrade affected Acrobat Reader DC installations according to Adobe guidance.
Reduce user exposure to untrusted PDFs from external links or unknown senders.
Prioritize managed endpoint update enforcement for high-risk user groups.
Validation and detection
Inventory Acrobat Reader DC versions across managed endpoints.
Flag versions 22.001.20085 and earlier, 20.005.3031x and earlier, and 17.012.30205 and earlier.
Confirm endpoints received Adobe’s applicable security update from APSB22-16.
Review email and web controls for handling untrusted PDF links.

CWE-657: Exact CWE lookup
Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references privilege impact, so privilege escalation and authorization behavior review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Violation of Secure Design Principles
Violation of Secure Design Principles represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
