Hayward is a Charter City of 62.55 square miles and 145,839 residents governed under the Council-Manager form of government. Hayward is known as the “Heart of the Bay” because of its central and convenient location in Alameda County – 25 miles southeast of San Francisco, 14 miles south of Oakland, 26 miles north of San Jose and 10 miles west of the valley communities surrounding Pleasanton. Serviced by an extensive network of freeways and bus lines, Hayward has two BART stations (Hayward and South Hayward), an Amtrak station, and the Hayward Executive Airport, with easy access to San Francisco, Oakland, and San Jose airports. Hayward's Executive Airport is a general aviation facility utilized by a multitude of diverse aircraft ranging from corporate jets to flying for enjoyment in small privately-owned aircraft. It is considered by many to be the Bay Area’s premier executive general aviation airport and provides a wide variety of aviation services to aircraft operators. Hayward’s diversity is not only reflected in our residents, but also in the variety of outstanding businesses that have chosen to locate and maintain their enterprises in our community. The investment of business and industry in our community is appreciated and valued. Continued partnerships between business, residents, education, and government are essential to ensure Hayward’s ongoing success as the “Heart of the Bay” and to our growing reputation as being “Open for Business.”

Latest Global CVEs (Not Company-Specific)
Description
Sigstore Timestamp Authority is a service for issuing RFC 3161 timestamps. Prior to 2.0.3, Function api.ParseJSONRequest currently splits (via a call to strings.Split) an optionally-provided OID (which is untrusted data) on periods. Similarly, function api.getContentType splits the Content-Type header (which is also untrusted data) on an application string. As a result, in the face of a malicious request with either an excessively long OID in the payload containing many period characters or a malformed Content-Type header, a call to api.ParseJSONRequest or api.getContentType incurs allocations of O(n) bytes (where n stands for the length of the function's argument). This vulnerability is fixed in 2.0.3.

Description
Monkeytype is a minimalistic and customizable typing test. In 25.49.0 and earlier, there is improper handling of user input which allows an attacker to execute malicious javascript on anyone viewing a malicious quote submission. quote.text and quote.source are user input, and they're inserted straight into the DOM. If they contain HTML tags, they will be rendered (after some escaping using quotes and textarea tags).

Description
Taiko Alethia is an Ethereum-equivalent, permissionless, based rollup designed to scale Ethereum without compromising its fundamental properties. In 2.3.1 and earlier, TaikoInbox._verifyBatches (packages/protocol/contracts/layer1/based/TaikoInbox.sol:627-678) advanced the local tid to whatever transition matched the current blockHash before knowing whether that batch would actually be verified. When the loop later broke (e.g., cooldown window not yet passed or transition invalidated), the function still wrote that newer tid into batches[lastVerifiedBatchId].verifiedTransitionId after decrementing batchId. Result: the last verified batch could end up pointing at a transition index from the next batch (often zeroed), corrupting the verified chain pointer.
