——14In nopCommerce 4.50.1, an open redirect vulnerability can be triggered by luring a user to authenticate to a nopCommerce page by clicking on a crafted link.8dCVE-2026-411069.3 CRI41.3%
——12Url redirection to untrusted site ('open redirect') in M365 Copilot allows an unauthorized attacker to elevate privileges over a network.9dCVE-2026-149024.0 MED40.2%
——12An open redirect in Ivanti Xtraction before version 2026.2.1 allows a remote unauthenticated attacker to redirect users to arbitrary external URLs.1dCVE-2025-686167.5 HIG39.5%
——12WeasyPrint helps web developers to create PDF documents. Prior to version 68.0, a server-side request forgery (SSRF) protection bypass exists in WeasyPrint's `default_url_fetcher`. The vulnerability allows attackers to access internal network resources (such as `localhost` services or cloud metadata endpoints) even when a developer has implemented a custom `url_fetcher` to block such access. This occurs because the underlying `urllib` library follows HTTP redirects automatically without re-validating the new destination against the developer's security policy. Version 68.0 contains a patch for the issue.2dCVE-2026-75048.1 HIG39.4%
——12A flaw was found in Keycloak's URL validation logic during redirect operations. By crafting a malicious request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading to the exposure of sensitive information within the domain or facilitating further attacks. This vulnerability specifically affects Keycloak clients configured with a wildcard (*) in the "Valid Redirect URIs" field and requires user interaction to be successfully exploited.
The issue stems from a discrepancy in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a malicious redirect URL is constructed using multiple @ characters in the user-info section, Java's URI parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak's validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and incorrectly permits the malicious redirect.2dCVE-2022-289776.1 MED35.8%
——11HtmlUtil.escapeRedirect in Liferay Portal 7.3.1 through 7.4.2, and Liferay DXP 7.0 fix pack 91 through 101, 7.1 fix pack 17 through 25, 7.2 fix pack 5 through 14, and 7.3 before service pack 3 can be circumvented by using multiple forward slashes, which allows remote attackers to redirect users to arbitrary external URLs via the (1) 'redirect` parameter (2) `FORWARD_URL` parameter, and (3) others parameters that rely on HtmlUtil.escapeRedirect.8d
