Details

Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information across domains, or execute arbitrary code. (CVE-2023-5722,
CVE-2023-5724, CVE-2023-5728, CVE-2023-5729, CVE-2023-5730, CVE-2023-5731)

Kelsey Gilbert discovered that Firefox did not properly manage certain
browser prompts and dialogs due to an insufficient activation-delay. An
attacker could potentially exploit this issue to perform clickjacking.
(CVE-2023-5721)

Daniel Veditz discovered that Firefox did not properly validate a cookie
containing invalid characters. An attacker could potentially exploit this
issue to cause a denial of service. (CVE-2023-5723)

Shaheen Fazim discovered that Firefox did not properly validate the URLs
open by installed WebExtension. An attacker could potentially exploit this
issue to obtain sensitive information. (CVE-2023-5725)
