Affected versions of Atlassian Jira Server and Data Center allow remote attackers to redirect users to a malicious URL via a reverse tabnapping vulnerability in the Project Shortcuts feature. The affected versions are before version 8.5.15, from version 8.6.0 before 8.13.7, from version 8.14.0 before 8.17.1, and from version 8.18.0 before 8.18.1.

An issue was discovered in PrimeKey EJBCA before 7.6.0. When audit logging changes to the alias configurations of various protocols that use an enrollment secret, any modifications to the secret were logged in cleartext in the audit log (that can only be viewed by an administrator). This affects use of any of the following protocols: SCEP, CMP, or EST.

An issue was discovered in PrimeKey EJBCA before 7.6.0. CMP RA Mode can be configured to use a known client certificate to authenticate enrolling clients. The same RA client certificate is used for revocation requests as well. While enrollment enforces multi tenancy constraints (by verifying that the client certificate has access to the CA and Profiles being enrolled against), this check was not performed when authenticating revocation operations, allowing a known tenant to revoke a certificate belonging to another tenant.

An issue was discovered in PrimeKey EJBCA before 7.6.0. The General Purpose Custom Publisher, which is normally run to invoke a local script upon a publishing operation, was still able to run if the System Configuration setting Enable External Script Access was disabled. With this setting disabled it's not possible to create new such publishers, but existing publishers would continue to run.

An issue was discovered in PrimeKey EJBCA before 7.6.0. As part of the configuration of the aliases for SCEP, CMP, EST, and Auto-enrollment, the enrollment secret was reflected on a page (that can only be viewed by an administrator). While hidden from direct view, checking the page source would reveal the secret.

opensysusers through 0.6 does not safely use eval on files in sysusers.d that may contain shell metacharacters. For example, it allows command execution via a crafted GECOS field whereas systemd-sysusers (a program with the same specification) does not do that.

Knot Resolver before 5.3.2 is prone to an assertion failure, triggerable by a remote attacker in an edge case (NSEC3 with too many iterations used for a positive wildcard proof).

Istio is an open source platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Istio 1.11.0, 1.10.3 and below, and 1.9.7 and below contain a remotely exploitable vulnerability where an HTTP request with `#fragment` in the path may bypass Istio’s URI path based authorization policies. Patches are available in Istio 1.11.1, Istio 1.10.4 and Istio 1.9.8. As a work around a Lua filter may be written to normalize the path.

Istio is an open source platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. According to [RFC 4343](https://datatracker.ietf.org/doc/html/rfc4343), Istio authorization policy should compare the hostname in the HTTP Host header in a case insensitive way, but currently the comparison is case sensitive. The proxy will route the request hostname in a case-insensitive way which means the authorization policy could be bypassed. As an example, the user may have an authorization policy that rejects request with hostname "httpbin.foo" for some source IPs, but the attacker can bypass this by sending the request with hostname "Httpbin.Foo". Patches are available in Istio 1.11.1, Istio 1.10.4 and Istio 1.9.8. As a work around a Lua filter may be written to normalize Host header before the authorization check. This is similar to the Path normalization presented in the [Security Best Practices](https://istio.io/latest/docs/ops/best-practices/security/#case-normalization) guide.
