CVE-2026-47291: Remote Code Execution in the Windows HTTP.sys
The analysis describes the concrete attack vector: a specially crafted HTTP/1.x request over a TLS connection that triggers a memory access exception in kernel context, leading to system termination or, in the worst case, code execution with kernel privileges.
ZDI-26-678: Adobe Photoshop DCM File Parsing Integer Overflow Remote Code Execution Vulnerability
Exploitation requires user interaction (opening a crafted DCM file), which favours attacks via email attachments or web downloads; exploitation in the wild has not been observed so far.
ZDI-26-677: Adobe Photoshop DCM JPEG-LS Image Parsing Integer Overflow Remote Code Execution Vulnerability
The flaw sits in the parser for the DCM/JPEG-LS format that is common in medical and document imaging and that Photoshop opens, so the attack vector is a crafted image file rather than network access.
ZDI-26-679: Adobe Photoshop DCM JPEG Image Parsing Integer Overflow Remote Code Execution Vulnerability
The vulnerability requires user interaction and enables RCE in Adobe Photoshop when parsing DCM JPEG images.
ZDI-26-667: Adobe Acrobat Reader DC Annotation Use-After-Free Remote Code Execution Vulnerability
The flaw requires user interaction and has not been reported as actively exploited so far, so the risk is primarily managed via patch timing and email/web filtering.
ZDI-26-676: Adobe Acrobat Reader DC DigSig Use-After-Free Remote Code Execution Vulnerability
The flaw resides in the DigSig signature-verification component; since PDFs from email attachments or web downloads are the typical attack vector, merely opening a crafted file is enough to achieve code execution in the user context.
ZDI-26-675: Adobe Acrobat Reader DC Annotation Use-After-Free Remote Code Execution Vulnerability
The report describes a newly published ZDI vulnerability with no indication of active exploitation or KEV listing; the attack requires a user to open a crafted file or web page.
ZDI-26-673: Adobe Acrobat Pro DC Doc Object Use-After-Free Remote Code Execution Vulnerability
The vulnerability requires user interaction, making it attractive for phishing attacks.
ZDI-26-663: Adobe Acrobat Pro DC Annotation Use-After-Free Remote Code Execution Vulnerability
This is a targeted ZDI advisory with no indication of exploitation in the wild; exploitation strictly requires user interaction (opening a crafted file or visiting a malicious web page).
ZDI-26-661: Adobe Acrobat Reader DC Annotation Use-After-Free Remote Code Execution Vulnerability
ZDI-26-664: Adobe Acrobat Reader DC Annotation Use-After-Free Remote Code Execution Vulnerability
No evidence of active exploitation or KEV inclusion; exploitation requires user interaction.
ZDI-26-671: Adobe Acrobat Reader DC Dialog Object Type Confusion Remote Code Execution Vulnerability
The flaw requires user interaction and has no evidence of in-the-wild exploitation at publication time, so the risk stems primarily from the wide installation base of Adobe Reader on endpoints.
ZDI-26-658: Adobe Acrobat Pro DC JPEG Parsing Integer Overflow Remote Code Execution Vulnerability
The vulnerability allows code execution simply by opening a crafted JPEG file or visiting a manipulated web page , a classic entry point for phishing campaigns against office users.
ZDI-26-674: Adobe Acrobat Reader DC Annotation Out-Of-Bounds Write Remote Code Execution Vulnerability
The report describes a new out-of-bounds write vulnerability in Adobe Acrobat Reader DC's annotation processing, rated CVSS 7.8 for RCE, requiring user interaction.
ZDI-26-662: Adobe Acrobat Reader DC Annotation Use-After-Free Remote Code Execution Vulnerability
The flaw sits in the Reader's annotation handling and requires opening a crafted PDF or a malicious web page, which limits everyday exploitation risk but favours targeted spear-phishing.
ZDI-26-665: Adobe Acrobat Reader DC Annots Report Use-After-Free Remote Code Execution Vulnerability
Rapid7 Analysis: Microsoft SharePoint Remote Code Execution (CVE-2026-63520)
Beyond the plain patch information, the report provides a concrete, reproducible exploitation path via a crafted BDC model XML file that grants an authenticated user execution rights on the SharePoint server.
ZDI-26-659: Adobe Acrobat Reader DC JPEG2000 File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability
