### Summary The group data stored for users in the boltdb database (meta.db) is an append-list so group revocations/removals are ignored in the API. ### Details [SetUserGroups](https://github.com/project-zot/zot/blob/5e30fec65c49e3139907e2819ccb39b2e3bd784e/pkg/meta/boltdb/boltdb.go#L1665) is alled on login, but instead of replacing the group memberships, they are appended. This may be due to some conflict with the group definitions in the config file, but that wasn't obvious to me if it were the case. ### PoC Login with group claims, logout, remove the user from a group from at IdP and log in again, the API still grants access and the new list of groups is appended creating meaningless duplicate entries and no longer mathing the expected groups from the IdP. The behavior can be verified by seeing the API or UI still presenting images it should not or by viewing the data directly: `bbolt get meta.db UserData <user>`, eg: ![image](https://github.com/user-attachments/assets/3491cbd2-...

### Impact Users who use IAM OIDC custom resource provider package will download CA Thumbprints as part of the custom resource workflow, https://github.com/aws/aws-cdk/blob/d16482fc8a4a3e1f62751f481b770c09034df7d2/packages/%40aws-cdk/custom-resource-handlers/lib/aws-iam/oidc-handler/external.ts#L34. However, the current `tls.connect` method will always set `rejectUnauthorized: false` which is a potential security concern. CDK should follow the best practice and set `rejectUnauthorized: true`. However, this could be a breaking change for existing CDK applications and we should fix this with a feature flag. Note that this is marked as low severity Security advisory because the issuer url is provided by CDK users who define the CDK application. If they insist on connecting to a unauthorized OIDC provider, CDK should not disallow this. Additionally, the code block is run in a Lambda environment which mitigate the MITM attack. As a best practice, CDK should still fix this issue under a...

The propensity for users to enter customer data, source code, employee benefits information, financial data, and more into ChatGPT, Copilot, and others is racking up real risk for enterprises.

The stolen firewall data is thorough but more than 2 years old now, meaning that most organizations following even basic security practices face minimal risk, hopefully.

The cyber actor played a role in the Treasury breach as well as attacks on critical infrastructure, linked to China-backed advanced persistent threat (APT) group Salt Typhoon.

As the US faces “the worst telecommunications hack in our nation’s history,” by China’s Salt Typhoon hackers, the outgoing FCC chair is determined to bolster network security if it’s the last thing she does.

### Impact Enabling frame-ancestors: 'self' grants any JupyterHub user the ability to extract formgrader content by sending malicious links to users with access to formgrader, at least when using the default JupyterHub configuration of `enable_subdomains = False`. #1915 disables a protection which would allow user Alice to craft a page embedding formgrader in an IFrame. If Bob visits that page, his credentials will be sent and the formgrader page loaded. Because Alice's page is on the same Origin as the formgrader iframe, Javasript on Alice's page has _full access_ to the contents of the page served by formgrader using Bob's credentials. ### Workarounds - Disable `frame-ancestors: self`, or - enable per-user and per-service subdomains with `JupyterHub.enable_subdomains = True` (then even if embedding in an IFrame is allowed, the host page does not have access to the contents of the frame). ### References JupyterHub documentation on why and when `frame-ancestors: self` is insecure...

As LLMs broaden access to hacking and diversify attack strategies, understanding the thought processes behind these innovations will be vital for bolstering IT defenses.

Cybersecurity researchers have disclosed three security flaws in Planet Technology's WGS-804HPT industrial switches that could be chained to achieve pre-authentication remote code execution on susceptible devices. "These switches are widely used in building and home automation systems for a variety of networking applications," Claroty's Tomer Goldschmidt said in a Thursday report. "An attacker

Recent data breaches have highlighted the critical need to improve guest Wi-Fi infrastructure security in modern business environments. Organizations face increasing pressure to protect their networks while providing convenient access to visitors, contractors, temporary staff, and employees with BYOD. Implementing secure guest Wi-Fi infrastructure has become essential for authenticating access,
