Every once in a while I have a really stupid idea, and then I sit down to write out what it would look like, and immediately spot a flaw in it that renders the whole thing insecure.

One of these days, one of my bad ideas is going to look back at me as someone else's implementation, deployed to production.

Thank you to @certfi for the insights and detection methods!

Yesterday a user told me they couldn't log in to my parliamentary monitoring site. On investigating, I found that Microsoft email security was logging in on behalf of my user by executing a POST. This broke the single-use sign-on link. Executing POSTs is usually considered unacceptable, and in this way Microsoft again transgresses an important norm. Here's how to deal with the specific POST problem & what might be done about these transgressions in general:

Shitposting is valid pentesting apparently.

Cisco Zero-Day: ClamAV OLE2 File Format Decryption Denial of Service Vulnerability
CVE-2025-20128 (5.3 medium) A vulnerability in the Object Linking and Embedding 2 (OLE2) decryption routine of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an integer underflow in a bounds check that allows for a heap buffer overflow read.

The Cisco PSIRT is aware that proof-of-concept exploit code is available for the vulnerabilities that are described in this advisory.
The Cisco PSIRT is not aware of any malicious use of the vulnerabilities that are described in this advisory.

Two more Cisco security advisories:

• Cisco Meeting Management REST API Privilege Escalation Vulnerability CVE-2025-20156 (9.9 critical)
• Cisco BroadWorks SIP Denial of Service Vulnerability CVE-2025-20165 (7.5 high)

These two do not mention proof of concept or exploitation.
