paicoding commit b8206b9 through 903adce Predictable ZSXQ Account Credentials

paicoding from commit b8206b9 through commit 903adce uses predictable credentials for accounts created via ZSXQ login, because loginByZsxq derives both the username and password solely from the member's ZSXQ number. Unauthenticated attackers can read that number from the victim's /user/{userId} profile page, compute the credentials, and log in via /login/username to take over the account.

SvelteKit: Prerendered redirect paths can inject arbitrary rules into the `_redirects` file generated by `@sveltejs/adapter-cloudflare`

SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. From version 4.7.0 until versions 7.2.10 and 8.0.2, @sveltejs/adapter-cloudflare allowed an attacker-influenced link crawled during prerendering to place whitespace, control characters, wildcards, or placeholders into a prerendered redirect path. The adapter wrote those paths into the Cloudflare _redirects output without output-context validation, allowing a path to create unintended routing rules that could redirect or expose requests beyond the intended prerendered route. This issue is fixed in 7.2.10 and 8.0.2.

AIOHTTP: Event loop stall in add_domain() wildcard matching

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, Application.add_domain() converts every asterisk wildcard in a domain mask into a greedy regular-expression fragment, so a mask containing two or more wildcards can take polynomial time to reject a long Host header that does not match. A remote attacker can repeatedly send such headers to a server configured with a multi-wildcard domain mask and stall the event loop. This issue is fixed in version 3.14.4.

AIOHTTP: Unbounded cookie storage in client CookieJar

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, Set-Cookie parsing treats unrecognized name=value attributes as additional cookies, while CookieJar does not limit the number of cookies stored or sent. A malicious server can make an aiohttp client accumulate a very large cookie set, consume memory and CPU repeatedly across redirects, and construct an excessively large Cookie header for later requests to the same domain. This issue is fixed in version 3.14.4.

MCUboot image hash span is not bounded against the slot, allowing a read past the flash area during image validation

bootutil_img_hash() computes the image digest over ih_hdr_size + ih_img_size + ih_protect_tlv_size bytes, all three taken from the candidate image's header, and reads that span out of the slot without checking that it fits in the flash area. The three sizes are also summed without an overflow check. Nothing earlier on the validation path bounds the whole span either: bootutil_img_validate() compares the image size against bootutil_max_image_size() only after the hash has been computed. The callers bound part of the span, or none of it: On the swap and overwrite upgrade path, boot_validate_slot() first runs the image header check (boot_is_header_valid(), later boot_check_header_valid()). Before MCUboot 2.2.0 that check covered only ih_hdr_size + ih_img_size, so for every image the protected-TLV area (ih_protect_tlv_size, a uint16_t, up to 65535 bytes) was hashed without being bounded. From 2.2.0 the check includes ih_protect_tlv_size, except for a compressed image in the secondary slot when MCUBOOT_DECOMPRESS_IMAGES (CONFIG_BOOT_DECOMPRESSION) is enabled, which leaves the same gap of up to 64 KB. Zephyr's single-slot and firmware loaders (boot/zephyr/single_loader.c, boot/zephyr/firmware_loader.c) read the header with boot_image_load_header(), which bounds ih_hdr_size + ih_img_size against the flash area. Before MCUboot 2.4.0 that bound did not include ih_protect_tlv_size, which leaves the same gap of up to 64 KB. From 2.4.0 these loaders bound the whole span. The serial recovery image-list and image-state handlers (bs_list() and bs_set() in boot/boot_serial/src/boot_serial.c) call bootutil_img_validate() with no header check at all, so on those paths ih_img_size is unbounded as well. The image is hashed before its signature is checked, so anyone who can place an image in a slot (an OTA or SMP update delivered through the application, or serial recovery) reaches this read before authentication. Whether a malformed header produces an actual read beyond the area depends on the flash backend: Backends whose flash_area_read() bounds-checks the request (Zephyr, Espressif, NuttX, Mbed) return an error once the chunked read crosses the end of the area. Validation fails and the image is rejected, with no over-read. With MCUBOOT_HASH_STORAGE_DIRECTLY (Zephyr CONFIG_BOOT_IMG_HASH_DIRECTLY_ON_STORAGE, available from 2.2.0, not enabled by default) the span is hashed through a single direct pointer into memory-mapped flash, with no bounds check. The Cypress PSoC6 port's flash_area_read() (boot/cypress/cy_flash_pal/cy_flash_map.c, from 1.6.0) does not bound the read: its assert()s compare against the area's absolute offset rather than its size, and it copies with memcpy(). The bytes read past the area feed only the digest, which is compared internally and never returned, so nothing is disclosed. The realistic effect is a read fault during image validation: up to 64 KB past the slot on the upgrade path and, before 2.4.0, on the Zephyr loaders, and potentially much further on the serial recovery handlers, which skip the header check. Where validation is repeated at every boot (a pending upgrade, or, before 2.4.0, the single-slot loader checking its image), the fault can recur on each reset and keep the device from booting. The fix makes bootutil_img_hash() add the three sizes with boot_u32_safe_add() and reject an image whose span, including the sector offset used in swap-using-offset mode, does not fit in the flash area, before any of it is hashed. Because the bound is applied where the bytes are read, it covers every caller.

Unchecked serial-recovery image index causes out-of-bounds slot-table read in MCUboot Zephyr port

MCUboot's Zephyr serial-recovery upload handler bs_upload() in boot/boot_serial/src/boot_serial.c decodes the host-supplied image field of an MCUmgr image-upload request into img_num (a full 32-bit value) and latches it on the off == 0 packet without any range check. It then passes img_num straight to flash_area_id_from_multi_image_slot(img_num, 0), which on the Zephyr port resolves to __flash_area_ids_for_slot() in boot/zephyr/include/sysflash/sysflash.h and indexes the static const int all_slots[] table as all_slots[img_num 2]. That table holds only MCUBOOT_IMAGE_NUMBER 2 entries, so any img_num >= MCUBOOT_IMAGE_NUMBER is an out-of-bounds read. The path is reachable by anyone with access to the serial / SMP recovery console, which is unauthenticated by design, and the bad value is supplied before any image signature is verified. The defect is specific to the default non-direct upload path (MCUBOOT_SERIAL_DIRECT_IMAGE_UPLOAD disabled) on the Zephyr port with the array-backed slot layout (not CONFIG_SINGLE_APPLICATION_SLOT). It is not gated on a multi-image configuration: MCUBOOT_IMAGE_NUMBER defaults to 1, so even a default single-image build is affected for any image >= 1. The MCUBOOT_SERIAL_DIRECT_IMAGE_UPLOAD path is safe (its flash_area_id_from_direct_image() switch returns -EINVAL for unknown indices). flash_area_id_from_multi_image_slot() takes a signed int image_index while img_num is uint32_t, so the attacker controls the sign of the index as well as its magnitude: an image of 0xFFFFFFFE converts to -2 and reads all_slots[-4], off the front of the table, while large positive values read off the end (CWE-192). (0xFFFFFFFF itself is the "no image given" sentinel and selects image 0.) Either way the index multiply img * 2 is performed in int, so a wild offset yields a bus/hard fault, giving a reliable denial of service of the bootloader during recovery. For moderately out-of-range indices the read returns adjacent .rodata as a garbage flash-area id that is handed to flash_area_open(); this normally fails with MGMT_ERR_EINVAL, but if the garbage id happens to match a valid non-image partition, the subsequent erase/write can target a partition outside the image set (CWE-787). The attacker-supplied value is never echoed back, so there is no information disclosure. The fix is to reject img_num >= BOOT_IMAGE_NUMBER on the off == 0 packet, before the slot lookup. The comparison must be made on the unsigned img_num: an equivalent guard applied after the conversion to int would not reject the negative case above. __flash_area_ids_for_slot() should bounds-check its own arguments as defence in depth. This vulnerability was reported independently twice: by NVIDIA Project Vanessa on 2026-06-22, and by Kai Phan (@kaimandalic) on 2026-07-19 as GHSA-8v33-88p6-jffj, which is closed as a duplicate of this advisory. Both original reports are reproduced in full below.
