Vulnerability from github – Published: 2023-02-10 19:54 – Updated: 2023-02-17 20:32Impact
Trying to read malformed HAMT sharded directories can cause panics and virtual memory leaks. If you are reading untrusted user input, an attacker can then trigger a panic.
This is caused by a bogus fanout parameter in the HAMT directory nodes. This includes checks returned in ipfs/go-bitfield GHSA-2h6c-j3gf-xp9r, as well as limiting the fanout to <= 1024 (to avoid attempts of arbitrary sized allocations).

GHSA-4GX2-PC4F-WQ37
Vulnerability from github – Published: 2026-04-08 00:12 – Updated: 2026-06-06 00:24Summary
When parse() fetches a URL that returns an HTML page containing a <meta http-equiv="refresh"> tag, it recursively calls itself with the redirect URL — with no depth limit, no visited-URL deduplication, and no redirect count cap. An attacker-controlled server that returns an infinite chain of HTML meta-refresh responses causes unbounded recursion, exhausting the Python call stack and crashing the process. This vulnerability can also be chained with the companion SSRF issue to reach internal network targets after bypassing the initial URL check.
Details
parse() catches ValueError on XML parse failure, extracts a meta-refresh URL from the HTML response via _extract_meta_refresh_url(), and tail-calls itself with that URL. The recursive call is unconditional — there is no maximum redirect depth, no set of already-visited URLs, and no guard against self-referential or looping redirects.
fastfeedparser/main.py — parse() (recursive sink):
def parse(source: str | bytes, ...) -> FastFeedParserDict:
is_url = isinstance(source, str) and source.startswith(("http://", "https://"))
if is_url:
content = _fetch_url_content(source)
try:
return _parse_content(content, ...)
except ValueError as e:
...
redirect_url = _extract_meta_refresh_url(content, source)
if redirect_url is None:
raise
return parse(redirect_url, ...) # ← unconditional recursion, no depth limit
_extract_meta_refresh_url() uses urljoin(base_url, match.group(1)) so relative, protocol-relative (//host/path), and absolute URLs in the content= attribute are all followed.
PoC
No live server required. The following monkeypatches _fetch_url_content to return an infinite HTML meta-refresh chain and confirms unbounded recursion:
import fastfeedparser.main as m
call_count = 0
_orig = m._fetch_url_content
def mock_fetch(url):
global call_count
call_count += 1
if call_count > 10:
raise RuntimeError(f"Stopped at call {call_count}")
next_url = f"http://169.254.169.254/step{call_count}/"
return f"""<html><head>
<meta http-equiv="refresh" content="0; url={next_url}">
</head><body>not a feed</body></html>""".encode()
m._fetch_url_content = mock_fetch
try:
m.parse("http://attacker.com/loop")
except RuntimeError as e:
print(f"CONFIRMED infinite loop: {e}")
finally:
m._fetch_url_content = _orig
print(f"Total fetches before stop: {call_count}")
# Output:
# CONFIRMED infinite loop: Stopped at call 11
# Total fetches before stop: 11
Each recursive call performs a real HTTP request (30 s timeout), HTML parsing, and a Python stack frame allocation. With Python's default recursion limit of 1000 and a 30 s per-request timeout, a single attacker request can hold a server thread busy for up to ~8 hours before a RecursionError is raised.
SSRF chain variant: The first response can be legitimate HTML redirecting to an internal address (http://192.168.1.1/), letting the redirect loop also serve as an SSRF bypass for targets that would otherwise be blocked by application-level URL validation applied only to the initial URL.
Impact
This is a denial-of-service vulnerability with a secondary SSRF-chaining impact. Any application that accepts user-supplied feed URLs and calls fastfeedparser.parse() is affected — including RSS aggregators, feed preview services, and "subscribe by URL" features. An attacker with no authentication can:
- Hold a server worker thread indefinitely (one request per attacker connection)
- Crash the worker process via
RecursionErrorafter ~1000 redirects - Use the redirect chain to pivot SSRF requests to internal network targets

Vulnerability from github – Published: 2022-05-13 01:35 – Updated: 2022-05-13 01:35Receipt of specially crafted UDP/IP packets over MPLS may be able to bypass a stateless firewall filter. The crafted UDP packets must be encapsulated and meet a very specific packet format to be classified in a way that bypasses IP firewall filter rules. The packets themselves do not cause a service interruption (e.g. RPD crash), but receipt of a high rate of UDP packets may be able to contribute to a denial of service attack. This issue only affects processing of transit UDP/IP packets over MPLS, received on an interface with MPLS enabled. TCP packet processing and non-MPLS encapsulated UDP packet processing are unaffected by this issue.

Mitigation
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.
Mitigation
- Mitigation of resource exhaustion attacks requires that the target system either:
- The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
- The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
- recognizes the attack and denies that user further access for a given amount of time, or
- uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Ensure that protocols have specific limits of scale placed on them.
Mitigation
Ensure that all failures in resource allocation place the system into a safe posture.
CAPEC-147: XML Ping of the Death
An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
CAPEC-227: Sustained Client Engagement
An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.
CAPEC-492: Regular Expression Exponential Blowup
An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
