The Instant Images – One Click Image Uploads from Unsplash, Openverse, Pixabay and Pexels plugin for WordPress is vulnerable to unauthorized arbitrary options update due to an insufficient check that neglects to verify whether the updated option belongs to the plugin on the instant-images/license REST API endpoint in all versions up to, and including, 6.1.0. This makes it possible for authors and higher to update arbitrary options.

A use-after-free vulnerability was discovered in Adobe Flash Player before 28.0.0.161. This vulnerability occurs due to a dangling pointer in the Primetime SDK related to media player handling of listener objects. A successful attack can lead to arbitrary code execution. This was exploited in the wild in January and February 2018.

Integer overflow in Adobe Flash Player before 18.0.0.324 and 19.x and 20.x before 20.0.0.267 on Windows and OS X and before 11.2.202.559 on Linux, Adobe AIR before 20.0.0.233, Adobe AIR SDK before 20.0.0.233, and Adobe AIR SDK & Compiler before 20.0.0.233 allows attackers to execute arbitrary code via unspecified vectors.

Adobe Flash Player 18.x through 18.0.0.252 and 19.x through 19.0.0.207 on Windows and OS X and 11.x through 11.2.202.535 on Linux allows remote attackers to execute arbitrary code via a crafted SWF file, as exploited in the wild in October 2015.

Unspecified vulnerability in Adobe Flash Player before 11.3.300.271 on Windows and Mac OS X and before 11.2.202.238 on Linux allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted SWF content, as exploited in the wild in August 2012 with SWF content in a Word document.

Adobe Flash Player before 10.2.154.27 on Windows, Mac OS X, Linux, and Solaris and 10.2.156.12 and earlier on Android; Adobe AIR before 2.6.19140; and Authplay.dll (aka AuthPlayLib.bundle) in Adobe Reader 9.x before 9.4.4 and 10.x through 10.0.1 on Windows, Adobe Reader 9.x before 9.4.4 and 10.x before 10.0.3 on Mac OS X, and Adobe Acrobat 9.x before 9.4.4 and 10.x before 10.0.3 on Windows and Mac OS X allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted Flash content; as demonstrated by a Microsoft Office document with an embedded .swf file that has a size inconsistency in a "group of included constants," object type confusion, ActionScript that adds custom functions to prototypes, and Date objects; and as exploited in the wild in April 2011.

Unspecified vulnerability in Adobe Reader and Acrobat 9.x through 9.1.2, and Adobe Flash Player 9.x through 9.0.159.0 and 10.x through 10.0.22.87, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via (1) a crafted Flash application in a .pdf file or (2) a crafted .swf file, related to authplay.dll, as exploited in the wild in July 2009.

The C9 Admin Dashboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 1.3.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.

The Trash Duplicate and 301 Redirect plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'duplicates-action-top' action in all versions up to, and including, 1.9. This makes it possible for unauthenticated attackers to delete arbitrary posts/pages.

The ADFO – Custom data in admin dashboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'adfo_list' shortcode in all versions up to, and including, 1.9.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
