dottie.js: dottie.js: Unauthorized object modification via prototype pollution bypass
Dottie provides nested object access and manipulation in JavaScript. Versions 2.0.4 through 2.0.6 contain an incomplete fix for CVE-2023-26132. The prototype pollution guard introduced in commit `7d3aee1` only validates the first segment of a dot-separated path, allowing an attacker to bypass the protection by placing `__proto__` at any position other than the first. Both `dottie.set()` and `dottie.transform()` are affected. Version 2.0.7 contains an updated fix to address the residual vulnerability.
A flaw was found in dottie.js, a JavaScript library for nested object access and manipulation. An incomplete fix for a previous vulnerability allows a remote attacker to bypass prototype pollution protectio

dottie is vulnerable to Prototype Pollution bypass via non-first path segments in set() and transform()
### Summary
dottie versions 2.0.4 through 2.0.6 contain an incomplete fix for CVE-2023-26132. The prototype pollution guard introduced in commit `7d3aee1` only validates the first segment of a dot-separated path, allowing an attacker to bypass the protection by placing `__proto__` at any position other than the first.
Both `dottie.set()` and `dottie.transform()` are affected.
### Details
The existing guard checks only `pieces[0] === '__proto__'`. When a path like `'a.__proto__.polluted'` is used, `pieces[0]` evaluates to `'a'`, not `'__proto__'`, so the guard is bypassed.
Inside the traversal loop, `current['__proto__'] = {}` triggers the `__proto__` setter, replacing the intermedi

Microsoft on Tuesday released 84 patches affecting 15 product families – including a few you’ve possibly never encountered. Eight of the addressed issues are considered by Microsoft to be of Critical severity, though none of those affect Windows, nor are they expected to be exploited within the next 30 days. In addition, five of those Critical issues were in fact addressed by Microsoft in advance of Patch Tuesday itself, as we’ll discuss below. Twenty-two have a CVSS base score of 8.0 or higher, including one with a 9.8 base score. None are known to be under active exploit in the wild, but two are publicly disclosed so far.
At patch time, six CVEs are judged more likely to be exploited in the next 30 days by the company’s estimation. Various of this month’s issues are amenable
